There's no doubt iOS 13 has dominated the talk around the Apple community this month. Since the announcement and release of the first developer beta, we iPhone users have had a treasure trove of new features and changes to explore and discuss. Now the fun continues with iOS 13 dev beta 2. Who's ready to start up the conversation all over again?
Keep in mind, this isn't the public beta. So far, Apple has only released the iOS 13 beta for developers. If you're thinking to yourself, "Wait, I'm not a developer, but I'm running iOS 13 ..." that's because Apple only gives direct access to the iOS 13 IPSW file to developer accounts. You likely have a friend who is a developer or you took an extra step to find the IPSW file somewhere on the World Wide Web.
This newest beta update comes with quite a lot of changes. Right off the bat, beta 2 adds Portrait Mode lighting control and the new High-Key Mono Portrait Mode, two features that were left out of dev beta 1. But that's not all. Here are all the new features we know about with dev beta 2:
- Unique Tapback sounds, one for each Tapback.
- New "Send Replies Without Confirmation" option when crafting messages with Siri.
- High-Key Mono Portrait Mode.
- Portrait Mode lightning control.
- Screen Time Downtime settings will sync to your Apple Watch.
- Apple Maps has a refreshed on boarding screen.
- "Select All" is back in Mail.
- Four new Memoji stickers.
- New Parallax toggle when choosing Wallpapers.
- Calendar has new color and interface changes.
- Files now supports connecting to SMB and APFS.
- Notes app has new selections for Notes and checklists
- Safari now has a "Show Link Preview" toggle in settings.
- New sound when accessing contextual menus via long-press.
- Voice Control has an icon in the top-left corner when active.
- Refreshed "Now Playing" screen in CarPlay.
You'll also find a laundry list of bug fixes, from Books and CarPlay, to Maps and Messages. Check out the full release notes for iOS 13 dev beta 2 below:

- After upgrading to iOS 13 beta, locally-downloaded cloud items might move back to iCloud. (51306790)
Books - Resolved Issues
- Books and PDFs imported into the Books app upload to iCloud Drive as expected. (47124224)
- Books stored in iCloud Drive appear properly in Books. (48685806)

- iOS no longer displays a blank screen after using CarPlay. (51164072)
- You don't need to launch Maps before asking Siri for directions. (50860819)
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 CHHapticDynamicParameterID might result in playback artifacts. (50026384)
- The default value for audioBrightnessControl should be 0, not 1. (50310604)
- 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
- Starting a CHHapticPatternPlayer multiple times properly restarts playback rather than stacking multiple playbacks together. (50878861)
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 - Known Issues
- Media services might unexpectedly quit 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 Media - Resolved Issues
- You no longer experience interruptions when attempting to play Amazon Prime Video. (46791204)
- Support for low-latency HLS is now available in iOS & iPadOS 13 beta. (51241703)
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

- On the home screen, you can adjust playback volume while a track is paused. (50389611)
- When using right-to-left languages, opening a folder from the Home screen that contains multiple pages of apps launches to the rightmost page, as expected. (50365467)
- While Airplane Mode is enabled, you're no longer prompted to turn Wi-Fi on even though it's already on. (51080243)
- When you drag content into Split View or Slide Over, targetContentIdentifier and UISceneActivationConditions predicates are used to select an appropriate window scene. (50784657)
- If the Quick Action menu is invoked on an app that has a badged icon, the badge doesn't layer behind the icon until the Quick Action menu is dismissed. (48374339)

- 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
- You don't receive an error when trying to sign into iCloud while attempting to restore from a backup. (49716545)

Siri - Known Issues
- 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)
- To properly support Announce Messages with Siri in your messaging app, add INSearchForMessagesIntentIdentifier to your notification category. (50462393)
- 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)

- Shortcuts are available when using Siri on Apple Watch, HomePod, and CarPlay. (50782908)
- Shortcuts synced to a device running iOS & iPadOS 13 beta from iOS 12 using iCloud Sync behave correctly. (50557374)
SwiftUI - Known Issues
- Text in previews in Xcode might not switch to the correct appearance in Dark Mode. (51486412)
- Return types for View modifier methods include complex generic types. In a future release, these methods will return simpler types. (46140669)
- The tabItemLabel(_:) modifier doesn't accept @ViewBuilder closures. Workaround: Wrap the views you pass to the modifier in a VStack:
- 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 Form view is now available. (50871134)

- Audio might not play in Instagram stories. (50433755)
- The Wells Fargo app might quit unexpectedly when opened or during sign-in. (51085418)
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.

- 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.

- 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)

To download and update your iPhone to iOS 13 dev beta 2, you will first need to be a registered developer with a valid configuration profile. You'll then need to download the profile for beta 2 from Apple's developer's site, either via the iPhone in Safari or another browser. Your system will ask if you want to install the profile. Say "Allow," then "Install" the new profile from Settings –> General –> Profiles. Restart when prompted, then you can check for OTA updates in "Software Update" to download and install beta 2. )You can also just download the restore image like was needed for dev beta 1.)
