warning emitted: CGAffineTransformInvert: singular matrix

lingolab2 commented 4 years ago

I get following warning when pushing or popping from NavigationStack

[90654:2639075] [Unknown process name] CGAffineTransformInvert: singular matrix. Am I doing something wrong here: ``` PushView(destination:SettingsView()) { VStack { Image(systemName: "gear") .resizable() .scaledToFit() .clipShape(Rectangle()) .shadow(color: .primary, radius: 5) .padding([.horizontal, .top], 7) Text("Settings").lineLimit(1) } .frame(minWidth: 50, maxWidth:100, alignment: .center) } PopView { Text("<-") } ```

Hi @lingolab2, sorry for the late response. I tried your code in a minimum viable example (shown below) and I didn't get any warning from xCode (with xCode v11.5):

import SwiftUI
import NavigationStack

struct Root: View {
    var body: some View {
        NavigationStackView {
            ZStack {
                Color.green.edgesIgnoringSafeArea(.all)
                PushView(destination:ChildView()) {
                    VStack {
                        Image(systemName: "gear")
                            .resizable()
                            .scaledToFit()
                            .clipShape(Rectangle())
                            .shadow(color: .primary, radius: 5)
                            .padding([.horizontal, .top], 7)
                        Text("Settings").lineLimit(1)
                    }
                    .frame(minWidth: 50, maxWidth:100, alignment: .center)
                }
            }
        }
    }
}

struct ChildView: View {
    var body: some View {
        ZStack {
            Color.yellow.edgesIgnoringSafeArea(.all)
            PopView {
                Text("<-")
            }
        }
    }
}

struct Transition_Previews: PreviewProvider {
    static var previews: some View {
        Root()
    }
}

You can copy paste my example and everything should be fine. Probably your issue doesn't strictly depend on the code you showed me. If you can show me more code (which still generates the problem) I'll try to help you. Thank you.
