How to let users edit your navigation title

Paul Hudson    @twostraws   

Updated for Xcode 14.2

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)
        }
    }
}
