Given a SwiftUI sheet with presentation detent(s):

struct ContentView: View {
    @State var isSheetOpen = false
    var body: some View {
        Button("Open Sheet") {
            isSheetOpen = true
        }
        .sheet(isPresented: $isSheetOpen) {
            Color.black
                .presentationDetents([.medium])
        }
    }
}

If you:

open the sheet
close it and rapidly open it again

the second presentation will ignore the detent and open a full screen sheet instead.

Xcode 16.3, iOS 18.4

This problem appeared with iOS 18.

As one of the workarounds, you can add a delay before giving the option to open it again.
