How to let users edit your navigation title

Updated for Xcode 15

SwiftUI's NavigationStack can display a simple string by using navigationTitle(), but that same modifier can also accept a string binding so the user can edit the title by tapping on it.

Important

Navigation title editing only works when your navigation bar is operating in inline mode. As far as I know, it works only on iOS and iPadOS.

For example, this shows a default title of “Welcome”, but users can tap that title to change it:

struct ContentView: View {
    @State private var title = "Welcome"

    var body: some View {
        NavigationStack {
            Text("Hello, world!")
                .navigationTitle($title)
                .navigationBarTitleDisplayMode(.inline)
        }
    }
}

If your title is there because it represents the name of some content your user is editing, I would recommend adding .toolbarRole(.editor) so that your title is aligned to the leading edge like other document titles:

struct ContentView: View {
    @State private var title = "Welcome"

    var body: some View {
        NavigationStack {
            Text("Hello, world!")
                .navigationTitle($title)
                .navigationBarTitleDisplayMode(.inline)
                .toolbarRole(.editor)
        }
    }
}
