I’m getting Auto Layout constraint conflict warnings related to AVPlayerView in my project. I’ve reproduced the issue on macOS Tahoe 26.2. The conflict appears to originate inside AVPlayerView itself, between its internal subviews, rather than in my own layout code. This issue can be easily reproduced in an empty project by simply adding an AVPlayerView as a subview using the code below. class ViewController: NSViewController { override func viewDidLoad() { super.viewDidLoad() let playerView = AVPlayerView() view.addSubview(playerView) } } After presenting that view controller, the following Auto Layout constraint conflict warnings appear in the console: Conflicting constraints detected: <decode: bad range for [%@] got [offs:346 len:1057 within:0]>. Will attempt to recover by breaking <decode: bad range for [%@] got [offs:1403 len:81 within:0]>.

And/or, set a symbolic breakpoint on LAYOUT_CONSTRAINTS_NOT_SATISFIABLE to catch this in the debugger. Is it system bug or maybe someone knows how to fix that? Thank you.

Our app has an architecture based on ViewModels. Currently, we are working on migrating from the ObservableObject protocol to the Observable macro (iOS 17+). The official docs about this are available here: https://developer.apple.com/documentation/swiftui/migrating-from-the-observable-object-protocol-to-the-observable-macro Our ViewModels that were previously annotated with @StateObject now use just @State, as recommended in the official docs. Some of our screens (a screen is a SwiftUI view with a corresponding ViewModel) are presented modally. We expect that after dismissing a SwiftUI view that was presented modally, its corresponding ViewModel, which is owned by this view (via the @State modifier), will be deinitialized. However, it seems there is a memory leak, as the ViewModel is not deinitialized after a modal view is dismissed. Here's a simple code where ModalView is presented modally (through the .sheet modifier), and ModalViewModel, which is a @State of ModalView, is never deinitialized. import SwiftUI import Observation @Observable final class ModalViewModel { init() { print("Simple ViewModel Inited") } deinit { print("Simple ViewModel Deinited") // never called } } struct ModalView: View { @State var viewModel: ModalViewModel = ModalViewModel() let closeButtonClosure: () -> Void var body: some View { ZStack { Color.yellow .ignoresSafeArea() Button("Close") { closeButtonClosure() } } } } struct ContentView: View { @State var presentSheet: Bool = false var body: some View { Button("Present sheet modally") { self.presentSheet = true } .sheet(isPresented: $presentSheet) { ModalView { self.presentSheet = false } } } } #Preview { ContentView() } Is this a bug in the iOS 17 beta version or intended behavior? Is it possible to build a relationship between the View and ViewModel in a way where the ViewModel will be deinitialized after the View is dismissed? Thank you in advance for the help.

Hello, community and Apple engineers. I need your help. Our app has the following issue: NavigationStack pushes a view twice if the NavigationStack is inside TabView and NavigationStack uses a navigation path of custom Hashable elements. Our app works with issues in Xcode 18 Beta 13 + iOS 18.0. The same issue happened on previous beta versions of Xcode 18. The issue isn’t represented in iOS 17.x and everything worked well before iOS 18.0 beta releases. I was able to represent the same issue in a clear project with two simple views. I will paste the code below. Several notes: We use a centralised routing system in our app where all possible routes for navigation path are implemented in a View extension called withAppRouter(). We have a enum RouterDestination that contains all possible routes and is resolved in withAppRouter() extension. We use Router class that contains @Published var path: [RouterDestination] = [] and this @Published property is bound to NavigationStack. In the real app, we need to have an access to this path property for programmatic navigation purposes. Our app uses @ObservableObject / @StateObject approach. import SwiftUI struct ContentView: View { @StateObject private var router = Router() var body: some View { TabView { NavigationStack(path: $router.path) { NavigationLink(value: RouterDestination.next, label: { Label("Next", systemImage: "plus.circle.fill") }) .withAppRouter() } } } } enum RouterDestination: Hashable { case next } struct SecondView: View { var body: some View { Text("Screen 2") } } class Router: ObservableObject { @Published var path: [RouterDestination] = [] } extension View { func withAppRouter() -> some View { navigationDestination(for: RouterDestination.self) { destination in switch destination { case .next: return SecondView() } } } } Below you can see the GIF with the issue: What I tried to do: Use iOS 17+ @Observable approach. It didn’t help. Using @State var path: [RouterDestination] = [] directly inside View seems to help. But it is not what we want as we need this property to be @Published and located inside Router class where we can get an access to it, and use for programmatic navigation if needed. I ask Apple engineers to help with that, please, and if it is a bug of iOS 18 beta, then please fix it in the next versions of iOS 18.0
