Adding environment value openURL or dismiss to a View in a NavigationStack, without even using it, causes an infinite refresh loop.
What doesn't work:
a)
struct ViewA: View {
@State private var path = NavigationPath()
var body: some View {
NavigationStack(path: $path) {
ViewB()
}
}
}
struct ViewB: View {
@Environment(\.openURL) var openURL
var body: some View {
NavigationLink("Next", value: 1)
.navigationDestination(for: Int.self, destination: itemView)
}
func itemView(_ item: Int) -> some View {
Text("Item \(item)")
}
}
Prints ViewB: _openURL changed. infinitely.
b) Passing the path to ViewB and appending the value with a Button
What works:
a)
.navigationDestination(for: Int.self) {
Text("Item \($0)")
}
Prints
ViewB: @self, @identity, _openURL changed.
ViewB: @self, _openURL changed.
ViewB: _openURL changed. (3 times)
b) Handling the destination on ViewA, which is not ideal for my use case.
Prints
ViewB: @self, @identity, _openURL changed.
ViewB: _openURL changed. (5 times)
While the workaround would work, it is still unclear how the environment value can cause the freeze (and eventual crash). Also that passing a function as parameter fails, while providing the destination in place does not. The code is stripped down to the minimal reproducible version. Any thoughts?
