I was seeing those same warnings here.

Thank you for the timely response. Here is the FB number: FB24136129

On visionOS 26.0.0 makeUIView(context:) will get called four times!

It looks like this was fixed. I see this behavior working as expected now on visionOS 26.4.

I submitted a feedback report for this: FB17020606.

I found it helpful to use this on the RealityView.

I am wondering about this as well.

Here is the reproducer. Create a basic visionOS app in Xcode. Place the ContentView in a NavigationView in the app file. Paste the code below in the ContentView When you run the app, press the "EmptyView" button. Click anywhere on the sidebar to see the warning appear in the console. The ContentView code: struct ContentView: View { var body: some View { List { NavigationLink("EmptyView") { EmptyView() } .isDetailLink(false) } .navigationTitle("Views") .navigationBarTitleDisplayMode(.large) } }

Continuing my previous post here, we submitted a feedback ticket for this: FB15732009. The crash that was posted in the original post that started this thread is slightly different than the crash I am seeing. This is the crash from the original post: Library not loaded: /System/Library/Frameworks/QuickLookUI.framework/Versions/A/QuickLookUI The crash I am seeing looks like this: Library not loaded: /System/iOSSupport/System/Library/Frameworks/_QuickLook_SwiftUI.framework/Versions/A/_QuickLook_SwiftUI The app that is crashing is using a dependency that we own and that dependency is using the quick look preview feature in SwiftUI. Which is probably why the quick look SwiftUI framework is being referenced in the crash log.

I archived our app using Xcode 16.1 and macOS 15.1, and it still crashes when it is run on macOS Ventura. Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: /System/iOSSupport/System/Library/Frameworks/_QuickLook_SwiftUI.framework/Versions/A/_QuickLook_SwiftUI

Thank you! Here is the crash log. crash_log.txt

That is good to know. I actually wanted the body of the if to be executed for visionOS but didn't understand why it was working. Thank you. Can you explain why this situation crashes? Also, I had this similar code that was distriubted via a xcframework and when that view is used in an app that is using the xcframework while running against visionOS there would be a runtime crash (EXC_BAD_ACCESS). The crash could only be reproduced when using that view from the xcframework and not the local source code. The problem was fixed by adding visionOS 1.0 to that availability check. But this shouldn't have been a crash in the first place.

Updated the original post: If you replace the MetalView() simply with EmptyView() it still shows a memory leak.
