Why does my SwiftUI app crash when navigating backwards after placing a `NavigationLink` inside of a `navigationBarItems` in a `NavigationView`?

Question

EDIT: This has been fixed in iOS 13.3!

Minimal reproducible example (Xcode 11.2 beta, this works in Xcode 11.1):

struct Parent: View {         


        

Answer 1

As a workaround, based on Chuck H's answer above, I've encapsulated the NavigationLink as a hidden element:

struct HiddenNavigationLink: View {
var destination: Content
@Binding var activateLink: Bool

var body: some View {
    NavigationLink(destination: destination, isActive: self.$activateLink) {
        EmptyView()
    }
    .frame(width: 0, height: 0)
    .disabled(true)
    .hidden()
}
}

Then you can use it within a NavigationView (which is crucial) and trigger it from a Button in a nav bar:

VStack {
    HiddenNavigationList(destination: SearchView(), activateLink: self.$searchActivated)
    ...
}
.navigationBarItems(trailing: 
    Button("Search") { self.searchActivated = true }
)

Wrap this in "//HACK" comments so when Apple fixes this you can replace it.
