I was trying to clone the swiftUI MapKit app however there is an issue that In iOS 16.0 NavigationLink has been deprecated (SearchView - line 108ish) with a such warning as 'init(tag:selection:destination:label:)' was deprecated in iOS 16.0: use NavigationLink(value:label:) inside a List within a NavigationStack or NavigationSplitView so how can i migrate the 'init(tag:selection:destination:label:)' to NavigationLink(value:label:) in this case
