t's very simple to test and very hard (at least for me) for found the solution.Just create a new Project and insert the next code in the AppDelegate:
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool { defer { restorationHandler(nil) } if userActivity.activityType == INStartCallIntentIdentifier { // Manage the open of the app when the user tap in a recent call from the native app Phone // of a call maded of this app } return true }When you run the app in iOS 13 (with the iPhone 11 in the Simulator in me case) then the app crash at the startup
This is the crash:
