Hi everyone! I've encountered an issue on Mac Catalyst: using the latest inspector modifier causes abnormal Sidebar and Columns state in NavigationSplitView. Sample Code: struct ContentView: View { @State private var isPresented = false var body: some View { NavigationSplitView { List { ForEach(0..<20, id: \.self) { item in Text("Item \(item)") } } } content: { List { ForEach(0..<20, id: \.self) { item in Text("Item \(item)") } } } detail: { List { } } .inspector(isPresented: $isPresented) { Form { } } } } Steps to reproduce: Xcode 16 beta 7, create a new iOS project Paste the code above Enable Mac Catalyst Run on Mac (macOS 15 beta 9) Press Command+N three times to open 3 new windows Click the Sidebar Toggle button The issue occurs (see screenshot below) Through testing, I found that as long as the inspector modifier is attached, the issue occurs. Also, the problem only appears in the 3rd and subsequent newly opened windows—the first two windows work as expected. FB20061521

The same project exports successfully when using Xcode 26.2 RC locally. Projects without Apple Watch app do not encounter this issue (not so sure about this). From Xcode Cloud UI: Exporting for App Store Distribution failed. Please download the logs artifact for more information. Run command: 'xcodebuild -exportArchive ...

Using Xcode 26.2 RC locally works around the issue.
