Apple's iOS 14 Developer Beta 3 for iPhone Includes New Clock Widget, Refreshed Music Icon & More

Apple just released iOS 14 developer beta 3 for iPhone today, Wednesday, July 22. The update comes 15 days after Apple released the second developer beta for iOS 14, and 13 days after the release of iOS 14 public beta 2.

Apple released this update at 10 a.m. PDT, the company's standard release time for developer beta updates. The keyword there is "developer," as this update is only for registered developers. If you're a public beta tester, you'll need to wait for Apple to release iOS 14 public beta 3, which we expect to see at 1 p.m. PDT today, or 10 a.m. PDT tomorrow.

Update: Apple's iOS 14 Developer Beta 4 for iPhone Now Available

So, what's new with dev beta 3? To start, Apple finally added the Clock widget in three different styles, as seen below. In addition, the Music icon is now red, reminiscent of a previous iOS Music icon.

Music gets a big update with beta 3. First of all, the icon is now red, as is the color scheme for the Music widgets. Music's menu button is now grey with red dots instead of the other way around. Music's Library section also has new icons, and you can now share Apple Music content to Snapchat stories, just like can you to Instagram or Facebook stories.

Apple also added a new splash screens when interacting with various parts of iOS for the first time. It also confirms that "jiggle mode" is now the official name when editing the home screen.

You also have a new mask option for Memoji. Before, you could only use the ruffled mask, but now you also have the option to choose a smooth mask.

In Today View, the Edit button is now permanently fixed at the bottom of the display. It also can be used to enter jiggle mode, and the "Customize" option is much clearer for adding and removing the older style of third-party widgets.

On beta 3, the Edit button makes all the widgets jiggle and the deprecated widget area is more clearly sectioned off. pic.twitter.com/M83390uaeg

Wallet - New Features in iOS & iPadOS 14 beta 2
Apple Pay support is now available to Mac Catalyst apps. Two methods have been added to existing delegate protocols. No changes are required for iPad apps, but one or both of these methods must be implemented when building for Catalyst. (64187739)

The first method is an addition to the PKPaymentAuthorizationControllerDelegate protocol: presentationWindowForPaymentAuthorizationController:. This method is required for Catalyst when using PKPaymentAuthorizationController, because PKPaymentAuthorizationController, unlike PKPaymentAuthorizationViewController, doesn't have knowledge of the window requesting presentation of the payment sheet. Pass back the UIWindow instance displaying the UI requesting the payment, for example, MyViewController.view.window. This method is marked as required when building for Catalyst, but is otherwise optional.

The second method depends on whether you're using PKPaymentAuthorizationController or PKPaymentAuthorizationViewController. For PKPaymentAuthorizationControllerDelegate, use paymentAuthorizationController(_:didRequestMerchantSessionUpdate:). For PKPaymentAuthorizationViewControllerDelegate, use paymentAuthorizationViewController(_:didRequestMerchantSessionUpdate:).

This method must be implemented to request a merchant session via your server, and return it via the handler. This mirrors the security model used in WebKit, and replaces listing merchant IDs in the app's Apple Pay entitlements. This method in turn uses the following class to send back results:
API_AVAILABLE(macos(10.16), ios(14.0), watchos(7.0))

@interface PKPaymentRequestMerchantSessionUpdate : NSObject

(instancetype)initWithStatus:(PKPaymentAuthorizationStatus)status

merchantSession:(nullable PKPaymentMerchantSession *)session;

@property (nonatomic, assign) PKPaymentAuthorizationStatus status;

@property (nullable, nonatomic, strong) PKPaymentMerchantSession *session;

@end
