News: Apple's iOS 13 Developer Beta 3 Available for iPhone, Packed with New Features & Changes

Apple's iOS 13 Developer Beta 3 Available for iPhone, Packed with New Features & Changes

On July 3, Apple pushed out iOS 13 developer beta 3 for iPhone, and there's a lot found hidden within. A new FaceTime setting, more Arcade details, full-page scrolling screenshots everywhere, a noise cancellation option in the Control Center, and a new markup tool — and that's just a few of the new features.

Right now, iOS 13 dev beta 3 is available on all iPhone models that support iOS 13 except the iPhone 7 and 7 Plus. It's not clear why Apple left these two models out high and dry in the newest beta version, but it will hopefully be resolved in upcoming releases.

While there are a lot of little changes in dev beta 3 — which came out just over a few weeks after dev beta 2 and over one week after public beta 1 — there are obvious ones worth calling out. We'll keep updating this post as we find new features, and you can read Apple's release notes at the end of this article.

Feature 1: FaceTime Attention Correction

There's a new setting in Settings –> FaceTime for "FaceTime Attention Correction." When you look at the front-facing camera on your iPhone during a FaceTime video call, it looks like you're doing so. With the feature enabled, however, iOS will auto-correct your eyes to make it look like you're staring at the recipient instead.

Feature 2: New Info About Arcade in the App Store

In previous betas, the "Arcade" tab was in the App Store app, but it just has some visuals and a "Coming Soon" in there. Now, there's a video preview and more information, as well as links to Apple's site to receive a notification when Arcade is ready.

Feature 3: Control HomeKit Devices with NFC Tags

You can now scan an NFC tag with your iPhone to turn on HomeKit devices. As seen in the tweet below, an iPhone, from the unlocked lock screen, scans an NFC tag and immediately turns on a HomeKit light.

Feature 4: Better Apps View in Shortcuts

When viewing "Apps" in the Shortcuts app, it now displays all supported apps instead of just App Store-related and "Open App" actions. Tapping any app will show you the available actions for each.

Feature 5: New Description for Headphone Audio Levels

Now when you go to Settings –> Privacy –> Health –> Headphone Audio Levels, the descriptions for both "Measure Levels" and "Include Other Headphones" are slightly different and list headphones models you've connected to in the past.

Beta 2 (left) vs. Beta 3 (right).

Feature 6: Purple Archive Button in Mail

Why? Who knows, but the "Archive" button that was once red is now purple.

Feature 7: New Background When Playing Audio Files in Files

In the Files app, when you tap to play an MP3 or another audio file type, it used to show you the QuickTime logo over a gray backdrop while it played. Now, it shows a sound wave on a white backdrop.

Beta 2 (left) vs. Beta 3 (right).

Feature 8: Opacity Tool Icon in Markup

The newer "Opacity" tool in the built-in Markup tools now has an icon next to it that looks like an empty box | filled box.

Beta 2 (left) vs. Beta 3 (right).

Feature 9: Improved Color Picker Icon in Markup

The circular icon for the color picker in the built-in Markup tools removed the big white border in between the selected color and the rest of the color wheel.

Beta 2 (left) vs. Beta 3 (right).

Feature 10: Mouse Cursor Sizes & Visibility

Instead of just being able to choose between small and big cursors when using a wired or wireless mouse with your iPhone, there are now ten different sizes to choose from. Plus, there's an option that lets you disable the cursor from auto-hiding or at least select the time frame for it to hide.

Beta 2 (left) vs. Beta 3 (right).

Other New Features in Beta 3

  • There's a new pop-up screen for Secure Recordings feature in the Home app for cameras.
  • A pop-up will appear in the Home app if you have security cameras letting you know that "Your Cameras Do Not Yet Support Secure Recording," if that's the case.
  • A pop-up for AirPods that will let you "Announce Messages with Siri: When your AirPods are connected, Siri can read incoming messages as they arrive and let you respond using just your voice."

How to Install iOS 13 Developer Beta 3

To update your iPhone to iOS 13 dev beta 3, you'll need to be a registered developer. You can use the restore image for your iPhone available in the Developer portal (install with iTunes or Finder) or install the configuration profile then update over the air. If you already have the profile installed, go to Settings –> General –> Software Update to begin the installation of the latest beta build, or you can wait until it installs automatically if "Automatic Updates" is enabled.

  • A new method is available for an AVAudioEngine-based app to retrieve a list of all nodes attached to an AVAudioEngine instance.
  • A new rendering mode in AVAudioEnvironmentNode selects the best spatial audio rendering algorithm automatically based on the output device.
  • A new AVAudioSession property allows system sounds and haptics to play while the session actively uses audio input.
  • A new enumeration, AVAudioSession.PromptStyle, informs apps which style of voice prompt they should play based on other audio activity in the system.
  • AVAudioSession.RouteSharingPolicy now permits apps to specify route-sharing policies so their audio and video routes to the same location as AirPlay.
  • Audio Unit Extensions now support user presets that are available across all host applications.

Audio - Deprecations

(51331268)

AVFoundation - New Features

  • AVFoundation now supports encoding video with alpha channels using HEVC. Videos encoded in this manner are broadly supported in AVFoundation APIs, and by Safari within web pages. Technical details of the format can be found in the Interoperability Profile specification. (8045917)

Books - Known Issues

  • After upgrading to iOS 13 beta, locally-downloaded cloud items might move back to iCloud. (51306790)

  • The garage door button might not appear in the CarPlay Dashboard. (50275274)

CarPlay - Resolved Issues

  • The map style for navigation apps changes dynamically between dark and light modes. (50986173)

Core Haptics - Known Issues

  • By default, haptics are disabled when microphone recording begins. You can override this by setting the AVAudioSession property allowHapticsAndSystemSoundsDuringRecording to true before activating its audio session. (25811898)
  • Events — such as audioContinuous, hapticContinuous, and audioCustom — can't be resumed during the event; no output occurs for that event, only for subsequent events. This applies to playback at a specific time offset, seeking, and resuming. (29274583)
  • When audio generated by Core Haptics is played using an audio session category or mode that normally supports Bluetooth or wired headphone output, no audio plays. (29939183, 50905288)
  • CHHapticDynamicParameter instances with nonzero relative times that are sent as part of a sendParameters(_:atTime:) call on a CHHapticAdvancedPatternPlayer with the atTime parameter set to 0.0 are incorrectly applied at the beginning of the CHHapticPattern, instead of the expected nonzero relative time. This doesn't occur on a CHHapticPatternPlayer. (46316890)
  • Both vibrations generated through AudioServicesPlaySystemSound(_:) and vibration patterns generated through the user-created tap-to-vibrate UI are attenuated when compared to prior versions of iOS. (47448156)
  • Parameter Curves are not supported with a CHHapticAdvancedPatternPlayer, only a CHHapticPatternPlayer. No error is generated when a CHHapticPattern containing a Parameter Curve is passed to a CHHapticAdvancedPatternPlayer. (47891515)
  • Brief audio distortion occurs when starting a Playback category app such as Music in the background. For example, brief distortion occurs if you start the app from Control Center while Core Haptics audio playback using a playAndRecord audio session is already underway. (48121467)
  • Following any decompression to uncompressed floating-point samples, the total limit on all audioCustom resources per process is eight megabytes. (48659023)
  • Multiple overlapping Parameter Curves for the same CHHapticDynamicParameter.ID might result in playback artifacts. (50026384)
  • Creating a hapticContinuous event with an attackTime of 1.0, and then dynamically increasing the attack time by 1.0, causes erroneous behavior. The expected behavior is the attack time should saturate at 1.0; therefore increasing the attack on an event that already has maximum attack (1.0) should have no effect. (50386282)
  • The maximum duration for a hapticContinuous haptic event is 30 seconds. Events exceeding this limit can be constructed and accepted by CHHapticPatternPlayer, but haptic playback will fade out after 30 seconds. (51322525)

Core Haptics - Resolved Issues

  • The default value for audioBrightnessControl is now 0, not 1. (50310604)

Core Image - New Features

  • The init(imageURL:options:) and init(imageData:options:) initializers no longer support RAW version 5 and earlier. Version 6 and later remain supported. (50911303)
  • Added new APIs for instantiating and modifying the built-in Core Image filters.
  • The CICoreMLModel filter is enhanced to support models with an input or output of type MLFeatureType.multiArray.
  • Metal CIKernel instances support arguments with arbitrarily structured data.
  • Metal CIKernel instances support returning a group of 2 × 2 pixels.
  • The integer values of CIFormat symbols, such as ARGB8, have changed to a new set of values that are consistent across platforms. The former values remain supported for backward compatibility; however, you should avoid dependancies on specific numerical values.

Core Media - Resolved Issues

  • Media services no longer quits with the message "AVFoundation error AVErrorMediaServicesWereReset -11819" when you play a low-latency HLS stream if the network link doesn't negotiate TCP ECN. (51690639)

Core ML - Known Issues

  • In the MLRecommender model, the exclude and restrict parameters are required, but they should be optional. For default behavior, pass in an empty list for restrict and the list of query items for exclude. (50348777)

Device Management - Known Issues

  • After completing User Enrollment, Reminders can't be enabled for the Managed Apple ID. (48820760)
  • Users can't accept an invitation to App and Book Assignments. (50832260)
  • MDM queries might return unmanaged data, such as profiles and certificates installed using Apple Configurator. (50857952)

Device Management - Resolved Issues

  • After completing User Enrollment, you're no longer prompted to reenter your Managed Apple ID credentials when viewing account details in Settings > Passwords & Accounts. (48605466)
  • You can now access the Enterprise iCloud Drive from managed apps when the managed "Open-in" restriction is enabled on a User Enrollment. (51016087)
  • On a User Enrollment, you can install enterprise apps after removing and then reenrolling in MDM. (50959631)

FaceTime - Known Issues

  • You might need to toggle the Attention Correction setting at least once in order to disable it. (52054477)

Files - Resolved Issues

  • Using Files in Schoolwork is now supported. (51588407, 51277263)

  • The "Notify when found" feature is currently unavailable.
  • Apple Pay cards might remain suspended after a device exits Lost Mode.
  • While iOS & iPadOS 13 remains in beta, offline-finding capability is limited.

Home Screen - Known Issues

  • Dragging app icons from Spotlight currently has no effect. Instead, drag app icons from the Dock. (49004339)
  • Some items in Quick Action menus have unexpectedly large icons. (50561570)

Home Screen - Resolved Issues

  • When viewing widgets for the first time after restarting your device, the Show More toggles appear correctly. (50966601)

iCloud - Known Issues

  • Under certain conditions, your iCloud Drive might be missing data after upgrading to iOS 13 beta. (51787170, 51950018) | Workaround: Recover deleted files on
  • Some documents might not download in iCloud Drive. (52295165)
  • The iCloud Drive section in Settings > General > iPhone Storage might inaccurately represent the current state of files on your device. (50362095)
  • When creating a new Pages, Numbers, or Keynote document in a shared folder, you might see the message: "Couldn't connect to iCloud." (50827963) | Workaround: Close and reopen the document.
  • When manually initiating iCloud backup from Settings > iCloud Account > iCloud > iCloud Backup > Back Up Now, the progress bar doesn't complete. However, this doesn't mean that the backup isn't complete. Once the text below the progress bar changes from "Backing Up" to "Updating iCloud," it indicates that the backup completed. However, the iCloud sync doesn't complete due an issue with notes syncing with iCloud. Your notes might not be up to date on iCloud compared to the notes on your device. (51030266)

iCloud - Resolved Issues

  • The content of folders inside an iCloud Shared Folder are available to other users viewing your shared folder. (51591135)
  • Pages, Numbers, and Keynote documents in shared folders correctly show an error message when you try to access them from (50738067)

Keyboards - Resolved Issues

  • You can disable QuickPath typing. (50989321)

Localization - Known Issues

  • Devices set to use certain languages might exhibit clipped or misaligned layout. (51068688)
  • Devices set to use certain languages might display unlocalized text. (47765173, 51197936, 51270878)

Location - Known Issues

  • Some apps that receive user location might be attributed large numbers of locations even though only a few locations were actually received. (52240105)

Location - Resolved Issues

  • Requesting Always authorization and receiving Provisional Always authorization is no longer incorrectly delivered to the CLLocationManagerDelegate as CLAuthorizationStatus.authorizedWhenInUse. (51475789)

Mail - New Features

  • Ignore Blocked Senders can now be enabled in Settings > Mail. The blocked contacts list is shared with Messages, FaceTime, and Phone. (50775961)

Mail - Known Issues

  • You might be unable to share an image directly from an email. Instead, forward the email with attachments. (50538771)

Maps - Resolved Issues

  • Route lines display correctly when sharing a trip ETA. (50904902)
  • You can navigate from an origin location that's different than your current location when a watch running watchOS 6 beta is paired to your iPhone running iOS 13 beta. (47399367)

Messages - Known Issues

  • If Animoji and Memoji aren't mirroring your face as expected, quit and reopen Messages. (52199654)

  • Music no longer appears paused even though audio is playing. (49926478)
  • You can share or tap album and artist links. (49675331)

Networking - New Features

  • All URLSessionTask instances with a GET HTTP method that contain a body now produce the error NSURLErrorDataLengthExceedsMaximum. (46025234)

Networking - Resolved Issues

  • For a background-configuration URLSession, an HTTP Set-Cookie header sent from a server behaves as expected. (47044416)

Networking - Deprecations

  • Removed support for FTP and File URL schemes for Proxy Automatic Configuration (PAC). HTTP and HTTPS are the only supported URL schemes for PAC. This affects all PAC configurations including, but not limited to, configurations set using Settings, System Preferences, Profiles, and URLSession APIs such as connectionProxyDictionary and CFNetworkExecuteProxyAutoConfigurationURL(_:_:_:_:). (28578280)
  • The URLSession and NSURLConnection APIs no longer support SPDY. Servers should use HTTP 2 or HTTP 1.1. (43391641)

Notes - Known Issues

  • Using search in Notes might produce unexpected results. (48238242)

Phone and FaceTime - Known Issues

  • When transitioning in and out of cellular service, the status bar might not accurately reflect the current connection state. (50821677)
  • When upgrading to iOS 13 beta, you might be unable to enter your SIM PIN during the setup process. Instead, use Settings > Cellular > SIM PIN to unlock your SIM. (51593059)

Podcasts - Resolved Issues

  • Transcript search is now available. (50425804)
  • Podcast artwork doesn't overlap other UI elements. (50859386)

Safari and WebKit - Known Issues

  • Keyboard shortcuts might not work when using non-English language settings. (50979111)

Screen Time - Known Issues

  • Users can select "One more minute" multiple times per day instead of only once each time they reach the limit for an app. (48773803)
  • If you enable Share Across Devices, Screen Time settings don't sync with iCloud until your iOS device is restarted. Any edits you make to your Screen Time settings on that device before restarting are lost. (50194586)

Settings - Known Issues

  • You might be unable to purchase cellular data plans on iPad. (51735832, 51737229)

Sign In with Apple - Known Issues

  • Real User status is currently unavailable. Sign In with Apple provides a status for new accounts but the status might return unexpected results. (51765525)

Siri - Known Issues

  • AirPods might disconnect unexpectedly when Announce Messages with Siri is enabled unless music is playing while receiving a new message. (50322025)
  • When you edit an app's intent definition file and install the app, changes aren't immediately reflected in Shortcuts. (46645833) | Workaround: Quit and relaunch Shortcuts after installing a new version of the app, or build and run the intents extension in Xcode, targeting the Shortcuts app.
  • The supportsOnDeviceRecognition property always returns false the first time it's accessed. After a few seconds, accessing it again returns the correct value. (47822242)
  • Shortcuts opened on iOS & iPadOS 13 beta are automatically upgraded and can no longer be opened on iOS 12. If a device with iOS 12 and a device with iOS 13 share an iCloud account, shortcuts might become unusable on the device running iOS 12. (50873839) | Workaround: Disable iCloud Sync between devices running iOS & iPadOS 13 beta and devices running iOS 12.
  • While using non-English languages, asking Siri to perform actions related to Reminders or Messages might cause the corresponding application to quit unexpectedly. (50952938)
  • Currently, the only supported response for INSearchForMediaIntent is INSearchForMediaIntentResponseCode.continueInApp. (51010311)
  • When Announce Messages with Siri is enabled, music playback might be interrupted when a message is read. (51243455)

Siri - Resolved Issues

  • Shortcuts-enabled media apps no longer appear to have SiriKit media support. (51010590)
  • To support Announce Messages with Siri in your messaging app, add INSearchForMessagesIntentIdentifier to your notification category. (50462393)

SwiftUI - New Features

  • You can style a NavigationView using two new style properties: stack and doubleColumn. By default, navigation views on iPhone and Apple TV visually reflect a navigation stack, while on iPad and Mac, a split-view styled navigation view displays. (51636729)
  • When using the doubleColumn style, you can provide two views when creating a navigation view — the first is the master and the second is the detail. For example:

NavigationView {

SwiftUI - Known Issues

  • Return types for View modifier methods include complex generic types. In a future release, these methods will return simpler types. (46140669)
  • Image instances don't use resizing information configured in asset catalogs. Configure the size of an image using the resizable(capInsets:resizingMode:) modifier instead. (49114577)
  • A ScrollView doesn't always size itself as expected for its content. (49204262) | Workaround: Size the view that's inside the ScrollView by applying the frame(width:height:alignment:) modifier to the inner view. (49204262)

SwiftUI - Resolved Issues

  • The tabItemLabel(_:) modifier — now named tabItem(_:) — now accepts @ViewBuilder closures. (51502668)
  • Text in previews in Xcode switch to the correct appearance in Dark Mode. (51486412)

Third-Party Apps - Known Issues

  • You might be unable to stream to a Chromecast device. (51334673)
  • WhatsApp might quit unexpectedly when forwarding messages to a user who isn't in the recent contacts list. (45416129)
  • WhatsApp users might receive duplicate notifications or notifications without content. (50537131)
  • Didi might not display map data. (48386075)
  • Audio might not play in Instagram stories. (50433755)
  • The Wells Fargo app might quit unexpectedly when opened or during sign-in. (51085418)

  • Gmail behaves as expected when you tap the "View entire message" link. (51451630)
  • Dragging and dropping an NSUserActivity-backed drag item creates a new scene.

UIKit - New Features

  • The UITableViewCell class no longer changes the backgroundColor or isOpaque properties of the contentView and any of its subviews when cells become highlighted or selected. If you are setting an opaque backgroundColor on any subviews of the cell inside (and including) the contentView, the appearance when the cell becomes highlighted or selected might be affected. The simplest way to resolve any issues with your subviews is to ensure their backgroundColor is set to nil or clear, and their opaque property is false. However, if needed you can override the setHighlighted(_:animated:) and setSelected(_:animated:) methods to manually change these properties on your subviews when moving to or from the highlighted and selected states. (13955336)
  • Since iOS 8, using UISearchController with UINavigationController has required setting the definesPresentationContext property of the top view controller to true. Failure to do so leads to subtle bugs that can be hard to detect and debug. Starting in iOS & iPadOS 13 beta, if a view controller's navigationItem has a non-nil searchController, when the view controller is shown in a navigation controller, UINavigationController automatically sets that view controller's definesPresentationContext property to true. If you are targeting earlier versions of iOS, set this property before your search controller becomes active. (31338934)
  • The UIRefreshControl class no longer directly modifies the contentInset of its scroll view. Instead, its adjustments to the content inset will be incorporated into the scroll view's adjustedContentInset. The only exception is when the scroll view's contentInsetAdjustmentBehavior is set to UIScrollView.ContentInsetAdjustmentBehavior.never, in which case the UIRefreshControl instance will modify the contentInset directly as it did in previous releases. (35866834)
  • If you implement self-sizing cells in a UITableView by overriding sizeThatFits(_:) without using Auto Layout, the height you return is interpreted as the desired height for the contentView of the cell, and UITableViewCell automatically adds any additional height needed to allow room for the cell separator. If you implement manual self-sizing this way, the cell's contentView width is guaranteed to be accurate for you to use in manual layout calculations when sizeThatFits(_:) is called on the UITableViewCell. (39742612)
  • Trait environments, such as views and view controllers, now have their traitCollection property populated with traits during initialization. These initial traits represent a prediction of the ultimate traits that the trait environment will receive when it gets added to the hierarchy. Because the traits that are populated during initialization are just a prediction, they might differ from the traits that are received once actually in the hierarchy. Therefore, when possible you should wait to perform work that uses the traitCollection until the view, or view controller's view, has moved into the hierarchy — meaning window returns a non-nil value — so that you don't have to throw away any work done using the predicted traits if the actual traits are different. The best time to use the traitCollection is during layout, such as inside layoutSubviews(), viewWillLayoutSubviews(), or viewDidLayoutSubviews().
  • The traitCollectionDidChange(_:) method is only called when the value of a trait changes. Importantly, because the trait collection is now initialized to a prediction of the ultimate traits in the destination hierarchy, when the initial predicted traits match the ultimate traits in the hierarchy, traitCollectionDidChange(_:) will not be called when the trait environment is added to the hierarchy. Because traitCollectionDidChange(_:) is intended to be an invalidation callback to notify you that one or more traits changed, audit your existing implementations of this method, as well as the UIContentContainer method willTransition(to:with:), for places where you might have been relying on it to trigger initial setup. The best place to lazily perform work that uses the traitCollection is inside one of the layoutSubviews methods discussed above, but remember that these layout methods are called any time layout occurs so be sure to avoid repeating work when you don't need to. (46818941)
  • You can now enable debug logging to easily see when traitCollectionDidChange(_:) or willTransition(to:with:) is called on your own classes. Turn on the logging by using the following launch argument: -UITraitCollectionChangeLoggingEnabled YES. You might want to temporarily disable the Main Thread Checker while using this launch argument and running your app from Xcode to avoid extra log messages for unrelated classes. (47858564)
  • The UITableViewCell class's contentView property is always laid out edge-to-edge with adjacent accessories, both on the leading and the trailing side. This streamlines the layout code so developers who want the correct default offset no longer have to align their content with the content view border or the layout margin depending on whether there is an accessory on the trailing side or not. You should now always lay out their code on the layout margins of the cell's content view to get the default system insets. These insets will be adjusted automatically based on the accessories visible in the cell to match the system's default spacing. (48214114)
  • You can now invoke a custom initializer from a creation block that's passed through instantiateInitialViewController(creator:) or instantiateViewController(identifier:creator:). This makes it possible for you to initialize view controllers with additional context and arguments, while taking advantage of defining them in a storyboard through Interface Builder. A custom controller initializer must call its super.init(coder:) method and pass the coder argument that it receives through the creation block. (48313869)

UIKit - Known Issues

  • Specifying UIWindowScene.DestructionRequestOptions in Swift is currently unavailable. (51036709)
