ios – SwiftUI view state resetting after alert is shown

Seeing an issue in iOS 26.2 iPhone 17 simulator (haven’t been able to reproduce on device), where a view’s state is reset after an alert is shown.

In this example the first LibraryView has the issue when alert is shown, the second LibraryView maintains state as expected.

struct ContentView: View {

    var body: some View {
        NavigationStack {
            List {
                VStack {
                    LibraryView(title: "Show view (Loss of state)")
                }
                
                LibraryView(title: "Show view (Works as expected)")
            }
        }
    }
}

/// This view is from a package dependency and wants to control the presentation of the sheet internally
public struct LibraryView: View {
    @State private var isPresented: Bool = false
    let title: String
    
    public init(title: String) {
        self.title = title
    }
    
    public var body: some View {
        Button(self.title) {
            self.isPresented = true
        }
        .sheet(isPresented: self.$isPresented) {
            ViewWithAlert()
        }
    }
}

private struct ViewWithAlert: View {
    @State private var isPresented: Bool = false
    @State private var presentedCount = 0
    
    var body: some View {
        Button("Show Alert, count: \(presentedCount)") {
            isPresented = true
            presentedCount += 1
        }
        .alert("Hello", isPresented: self.$isPresented) {
            Button("OK") { }
        }
    }
}

Any ideas?

The issue can be corrected by moving the .sheet to a higher level within the layout (i.e. on the NavigationStack). However, the library wants to control that presentation and not require the integration to present the sheet.
