NavigationLink's initializer init<S>(_ title: S, destination: Destination) where S : StringProtocol is deprecated and only available for iOS 13.0–15.2. The replacement is init<S>(_ title: S, destination: () -> Destination) where S : StringProtocol per the documentation: https://developer.apple.com/documentation/swiftui/navigationlink/init(_:destination:)-6hslu. Replacing my existing code with NavigationLink("MyTitle") { Text("MyView") } shows the error Type '() -> Text' cannot conform to 'View' 1. Only concrete types such as structs, enums and classes can conform to protocols 2. Required by generic struct 'NavigationLink' where 'Destination' = '() -> Text' What's wrong with my use of the recommended initializer? Using Xcode Version 12.5.1 (12E507). Here is the full view for reference: import SwiftUI struct Test: View {   var body: some View {     NavigationView {       NavigationLink("MyTitle") {         Text("MyView")       }     }   } }
