I'm working on a NavigationStack based app. Somewhere I'm using:
@Environment(\.dismiss) private var dismiss
and when trying to navigate to that view it gets stuck.
I used Self._printChanges() and discovered the environment variable dismiss is changing repeatedly. Obviously I am not changing that variable explicitly. I wasn't able to reproduce this in a small project so far, but does anybody have any idea what kind of thing I could be doing that might be causing this issue?
iOS 17.0.3
Have you found a solution?
@gbuela , have you found a solution?
Weirdly enough, for me it happened because I had an array of tuples inside my View.
You don't even have to use the array, just having it in the View was enough to cause the infinite loop:
struct SomeView: View {
...
var sections: [(String, String)] = [
("String 1", "value 1"),
("String 2", "value 2"),
("String 3", "value 3"),
("String 4", "value 4")
]
var body: some View {
...
}
}
I have a similar bug. It helped to put the data array inside an ObservableObject. The dismiss variable still seems to change 3-4 times when the view appears but after that it seems to stabilise
I just struggled with this problem for a while -- what has seemed to fix my problem was removing the @State property wrapper from variables that shouldn't have had the wrapper in the first place (Date, Timer...). Always heard that @State should only be used for simpler types but this is the first instance where it really gave me a headache... now I know, hopefully it saves someone else some time.
