    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)

(28578280)

  • The NSURLSession 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 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)

  • Do Not Disturb settings might not synchronize between your phone and watch until both are updated to iOS 13 beta 4 and watchOS 6 beta 4. (52830669)

  • 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 INSearchForMediaIntentResponseCodeContinueInApp. (51010311)

  • When Announce Messages with Siri is enabled, music playback might be interrupted when a message is read. (51243455)

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

Known Issues

  • When pushing a view from a NavigationLink in an element of a List, the pushed view shows Button instances with black text and NavigationLink instances with black text and a chevron. (52858284)

  • 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)

Resolved Issues

  • View modifier methods return opaque views (some View) rather than complex generic types. (46140669)

  • ScrollView instances always size themselves as expected for their content. (49204262)

  • 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)

Deprecations

  • 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)

  • Audio might not play in Instagram stories. (50433755)

  • The Wells Fargo app might quit unexpectedly when opened or during sign-in. (51085418)

Resolved Issues

  • 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 opaque 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 clearColor, 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 UIScrollViewContentInsetAdjustmentNever, 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 willTransitionToTraitCollection:withTransitionCoordinator:, 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 willTransitionToTraitCollection:withTransitionCoordinator: 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)

Known Issues

  • Prior to iOS 13, UITextField assumed that the frames of its leftView and rightView were correctly set when assigned and would never change. Starting in iOS 13, the implementation of leftViewRectForBounds: and rightViewRectForBounds: now ask the view for its systemLayoutSizeFittingSize:. To achieve the previous behavior when linking against and running on iOS 13, add explicit sizing constraints on the view, wrap it in a plain UIView, or subclass the view and implement systemLayoutSizeFittingSize:. (51787798)

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

Voice Control

Known Issues

  • After you enable Voice Control for the first time, resources begin downloading in the background. Once the download completes, you will receive a notification that Voice Control is ready for use. (50788121)

Voice Memos

Resolved Issues

  • Voice Memos synced from iCloud play correctly. (51492047)

Watch

Known Issues

  • Complications might disappear from Apple Watch after updating to iOS 13 beta if your watch isn't running watchOS 6 beta. (50507942)

Resolved Issues

  • Settings appear properly in the Apple Watch app if you’ve recently reinstalled a built-in app. (51689111)

Xcode

New Features

Known Issues

  • Donated shortcuts might not appear in Search while using the simulator. (50832782)

    Workaround: Test on a device with Settings > Developer > Display Recent Shortcuts enabled.

  • Changing the volume level in Simulator while a video is playing in Safari mutes the audio. (51207286)

Resolved Issues

  • Calls to SKProductsRequest no longer fail in Simulator. (50875951)

  • Swift interfaces for several new NSURLSession APIs are now available. (50517967)

  • Dark Mode is available in Simulator (50699968)

  • When running your app from Xcode, you no longer see console errors about UIKit classes that override the traitCollection getter. (51651561)
