When I run the code below, the trace, "Called", is shown 3-4 times initially. If I click on a color row, the trace shows 9 times. Why is that?
If I comment out the line, @Environment(\.dismiss) private var dismiss, the trace shows only 1 time, as expected.
I've read a number of reports regarding dismiss() which seems to be very brittle. It often causes an infinite loop. But I need to dismiss a view. Its older counterpart, @Environment(\.presentationMode), seems to cause infinite loop at times. Are there other ways to dismiss a view without suffering these issues?
struct TestNavigationLink: View {
@Environment(\.dismiss) private var dismiss
var body: some View {
let _ = print("Called")
NavigationStack {
List {
NavigationLink("Mint") { ColorDetail(color: .mint) }
}
.navigationTitle("Colors")
}
} // body
struct ColorDetail: View {
var color: Color
var body: some View {
color.navigationTitle(color.description)
}
}
}
