How to recommend another app using appStoreOverlay()

SwiftUI gives us a dedicated modifier that can recommend other apps on the App Store, which is a great way to cross-sell to users – “if you liked this, you’ll also like that”, and so on. This is particularly helpful if you’re using App Clips, where you can recommend the full app from your clip once your user has performed their primary action.

This modifier needs some state to watch that will determine whether the App Store overlay is active or not, along with an SKOverlay.AppConfiguration that determines which app to recommend.

Important: appStoreOverlay() is not available on macOS.

For example, this will recommend a particular app when the button is pressed:

struct ContentView: View {
    @State private var showRecommended = false

    var body: some View {
        Button("Show Recommended App") {
            showRecommended.toggle()
        }
        .appStoreOverlay(isPresented: $showRecommended) {
            SKOverlay.AppConfiguration(appIdentifier: "1440611372", position: .bottom)
        }
    }
}
