SwiftUI NavigationView/Stack if available iOS 15/16

Time:09-06

There's something I don't really understand about the transition from NavigationView to NavigationStack for SwiftUI 4 and iOS 16.

I have 2 applications running on the App Store (targeting iOS 15 and above) and of course I'm using NavigationView. This weekend, I was looking for a solution to have them ready for iOS 16 by replacing:

var body: some View {
   NavigationView {
      ScrollView { /* code here */ }
   }
}

To something like this:

var body: some View {
   if #available(iOS 16, *) {
      NavigationStack {
   } else {
      NavigationView {
   }
      ScrollView { /* code here */ }
   }
}

But finally, before doing so, I tried them with iOS 16 Beta and they're perfectly fine. I don't understand, I thought it would be total a mess but finally no. Do you have an explanation? Maybe, deprecated isn't what it should mean?

CodePudding user response:

NavigationView is deprecated, not obsoleted. When a component becomes deprecated, it still can be used until Apple decides to obsolete it which will cause a crash when used. Although it's functional, you shouldn't use it.
