I’m engaged on making a customized Popup View based mostly on a .fullscreenCover. The .fullscreenCover is used to put the Popup content material on display on a semi-transparent background.

Whereas this works on iOS 18, there’s a drawback on iOS 17: When the Popup content material accommodates a .sheet, the background is just not clear any extra however opaque.

1. Picture: iOS 17. When exhibiting the Popup an opaque background covers the principle content material. When tapping on the background it turns clear.
1. Picture: iOS 18. All the things works as meant. When exhibiting the Popup the principle background is roofed with a semi-transparent background.

Eradicating the .sheet(...) from the Popup content material solves the issue. It doesn’t matter if the sheet is used or not. Including it to the view code is sufficient to set off the issue.

Utilizing a .sheet inside a .fullscreenCover shouldn’t be an issue so far as I do know.

Is that this a bug in iOS 17 or is there one thing mistaken with my code?

Code:

struct SwiftUIView: View {
    @State var isPresented: Bool = false
    @State var sheetPresented: Bool = false
    
    var physique: some View {
        ZStack {

A number of pockets apps maintain a number of credentials
