Our app crashes when compiled with the iOS 27 beta 3 SDK and run as an iOS app on Mac, on both macOS 26 and macOS 27, as soon as a UISearchBar receives focus. The crash is due to this exception: *** Assertion failure in BOOL _screenBasedFocusUnsupported(void)(), UIScreen.m:3.725 Accessing the focus system through UIScreen is no longer supported.

I have a UICollectionView using a UICollectionViewCompositionalLayout with an orthogonally scrolling section. When selecting a cell, I present a modal view controller with a zoom transition. If I scroll quickly in that section after dismissing the presented view controller, the cells briefly overlap. See the attached screenshot. This issue occurs only on iOS 26 and does not occur on iOS 18. Has anyone found a way to mitigate this?

I can’t get UIScene-based state restoration to work on tvOS as it does on iOS. UISceneSession.stateRestorationActivity is always nil in UIWindowSceneDelegate.scene(_:willConnectTo:options:) despite UIWindowSceneDelegate.stateRestorationActivity(for:) being called in the previous lifecycle. The NSUserActivityType is correctly configured in the Info.plist. Has anyone encountered the same issue or knows how to get this to work?

We have a universal iOS/tvOS app that also supports iOS App on Mac. In our AVPlayer-based video player we support AirPlay with AVRouteDetector and AVRoutePickerView. We play HLS streams. When we try to AirPlay from an iOS device to an Apple TV or a Mac that has our app installed, it doesn't work. The receiver is marked as active in the route picker UI but the video doesn't show up on the receiver and playback stops. When our app isn't installed on the receiver device, everything works as expected. Has anyone encountered the same issue? Any solutions available for this?

Since August 27th 2024 Xcode Cloud fails to clone our Github repository. The reported error is LFS related: "smudge filter lfs failed" Nothing in our repository configuration has changed and the LFS files have been in place for a long time.

We encountered a deadlock scenario when our app runs on iOS 18. It happens when we use the async version of UICollectionViewDiffableDataSource.apply() and request a section snapshot from within the UICollectionViewCompositionalLayoutSectionProvider. The deadlock doesn't happen when using the completion handler version of UICollectionViewDiffableDataSource.apply() or when requesting a full snapshot from the data source. On iOS 17 there is no issue. import UIKit class ViewController: UICollectionViewController { private enum SectionIdentifier: Hashable { case test } private enum ItemIdentifier: Hashable { case test(UUID) } private typealias Snapshot = NSDiffableDataSourceSnapshot<SectionIdentifier, ItemIdentifier> private typealias SectionSnapshot = NSDiffableDataSourceSectionSnapshot<ItemIdentifier> private typealias DataSource = UICollectionViewDiffableDataSource<SectionIdentifier, ItemIdentifier> private lazy var dataSource: DataSource = { let cellRegistration = UICollectionView.CellRegistration<UICollectionViewCell, UIColor> { cell, _, color in cell.contentView.backgroundColor = color } return DataSource(collectionView: collectionView) { [weak self] collectionView, indexPath, itemIdentifier in return collectionView.dequeueConfiguredReusableCell(using: cellRegistration, for: indexPath, item: .red) } }() override func viewDidLoad() { super.viewDidLoad() collectionView.dataSource = dataSource collectionView.collectionViewLayout = UICollectionViewCompositionalLayout { [weak self] section, environment -> NSCollectionLayoutSection? in // calling `UICollectionViewDiffableDataSource.snapshot(for:)` from the `UICollectionViewCompositionalLayoutSectionProvider` leads to deadlock on iOS 18 let numberOfItems = self?.dataSource.snapshot(for: .test).items.count ?? 0 // deadlock // calling `UICollectionViewDiffableDataSource.snapshot()` causes no issue // let numberOfItems = self?.dataSource.snapshot().numberOfItems(inSection: .test) ?? 0 // works let item = NSCollectionLayoutItem(layoutSize: .init(widthDimension: .absolute(100), heightDimension: .absolute(100))) let group = NSCollectionLayoutGroup.horizontal(layoutSize: .init(widthDimension: .fractionalWidth(1), heightDimension: .absolute(100)), repeatingSubitem: item, count: numberOfItems) group.interItemSpacing = .fixed(5) return .init(group: group) } var snapshot = Snapshot() snapshot.appendSections([.test]) snapshot.appendItems([.test(UUID()), .test(UUID()), .test(UUID()), .test(UUID())]) // using the async wrapper `UICollectionViewDiffableDataSource.apply()` on any thread leads to deadlock on iOS 18 Task { await dataSource.apply(snapshot) } // deadlock // Task { @MainActor in await dataSource.apply(snapshot) } // deadlock // using `UICollectionViewDiffableDataSource.apply()` with completion handling causes no issue // Task { dataSource.apply(snapshot) } // works // dataSource.apply(snapshot) // works } } Full example project at https://github.com/antiraum/iOS18_UICollectionViewDiffableDataSource_deadlock

Play media intents suggested via INUpcomingMediaManager.setSuggestedMediaIntents(_:) have been shown on the iOS lock screen in past iOS versions. In iOS 16/17 play media intents seem to be only shown within the Siri suggestions in the spotlight overlay and in the Siri suggestion widget. When the intents were shown on the lock screen, it was possible to open a preview via long press. Similar to notification previews. Preview support could be implemented with an Intents UI extension. Is there still any place in current iOS versions where play media intents are surfaced and a preview can be opened? In the spotlight overlay a long press has no effect.

We don't have a suitable design for our widget for WidgetRenderingMode.vibrant as used on the iPad Lock Screen. Is there a way to opt out of having our widget available there? The iOS 17 photos widget seems to behave like this. It is available for iPhone StandBy, but not for iPad Lock Screen. This is the behaviour we want to have.

Running an app that uses AppleArchive with Xcode 14.0/14.1 on simulators with iOS/tvOS 14.x/15.x fails with a dyld linker error: Library not loaded: /usr/lib/swift/libswiftAppleArchive.dylib Referenced from: /Users/tom/Library/Developer/CoreSimulator/Devices/A35CB8BA-9ABF-4E4D-B985-FEF35091FB88/data/Containers/Bundle/Application/5A504371-0F53-4E06-9F46-81D73835E906/MyApp.app/MyApp Reason: tried: '/Users/tom/Library/Developer/Xcode/DerivedData/MyApp-ffndhzhjdbfrvuhkxftdfqudypxx/Build/Products/Debug-iphonesimulator/libswiftAppleArchive.dylib' (no such file), '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/introspection/libswiftAppleArchive.dylib' (no such file), '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftAppleArchive.dylib' (no such file), '/usr/lib/swift/libswiftAppleArchive.dylib' (no such file), '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/libswiftAppleArchive.dylib' (no such file) Running the app on iOS/tvOS 14.x/15.x devices works. Also release builds run fine on those devices. I'm unable to test if this issues was already present in Xcode 13, because running apps with AppleArchive on simulators fails because of another bug: https://developer.apple.com/forums/thread/665465 Feedback: FB11703995

When archiving and uploading a build of our tvOS app to App Store Connect with Xcode 13.3RC, it gets rejected with TMS-90562: Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path. When archiving and uploading with Xcode 13.2.1 the build is accepted and processed. I could not find any rpath issues when inspecting the binary with otool -L and otool -l. Has anyone else experienced the this issue with Xcode 13.3RC? I've filed feedback FB9952607

Does AppleTV 4K support HLG in any configuration? When I connect my AppleTV 4K to a Samsung TV with HLG support via HDMI AVPlayer.availableHDRModes.contains(.hlg) returns false However AVPlayer.availableHDRModes.contains(.hdr10) returns true https://support.apple.com/en-us/HT208074 only mentions HDR10 and Dolby Vision support. Is there any way to play HLG video on AppleTV 4K similar to how it works on newer iPhones and iPads?

The LD_RUNPATH_SEARCH_PATH in the build settings is correct and when inspecting the binary with otool -l the LC_RPATH entries are also correct. When archiving the app with Xcode 13.2.1, it runs fine on macOS Big Sur. Has anybody experienced the same and knows a workaround? I've filed a feedback: FB9951126
