M.Othman's answer for Swift 5. (Although using NSLog is not recommended anymore)
Add the following after you set everything needed to display your RootViewController
. In your application(_:didReceiveRemoteNotification)
, you should add the logic that can differentiate between a first launch and come to background type of launch.
if let launchOptions = launchOptions,
let notification = launchOptions[UIApplicationLaunchOptionsKey.remoteNotification]
as? [AnyHashable : Any] {
NSLog("app recieved notification from remote \(notification)")
self.application(application, didReceiveRemoteNotification: notification)
} else {
NSLog("app did not recieve notification")
}
