NavigationItem for SwiftUI

Why

SwiftUI doesn't expose the UINavigationItem from the NavigationView but sometimes you might want to access it to set the prompt or the backButtonDisplayMode. With this modifier you can easily customize the UINavigationItem of your SwiftUI NavigationViews.

Usage

The .navigationItem modifier has to be applied to the NavigationItem (or NavigationStack, NavigationSplitView when using iOS 16+) because otherwise the Environment will not be applied to the NavigationLink destinations. On child views you can apply them anywhere just like .navigationTitle

NavigationView {
    // content
}
.navigationItem { navigationItem in
    // Customize the NavigationItem here
    navigationItem.prompt = "Enter information"
    navigationItem.backButtonDisplayMode = .generic
}
