Open app in specific view when user taps on push notification with iOS Swift

Question

My app allows remote push notifications to a user. How do I enable it to be opened in a specific view controller when the user taps on the push notification? I want the app to open and navigate to a specific view controller depending on the push notification received.

To do this you need to set an identifier for each ViewController that your app may be opened with, and then check the payload in the launchOptions argument of application:didFinishLaunchingWithOptions: in your AppDelegate Here are the steps to doing this:

1. In your PFPush, use setData to add a key to your payload with the identifier: notification.setData(["alert":"your notification string", "identifier":"firstController"])

2. Set the identifier on each ViewController by selecting it and changing the following values

3. Make your Push Notification send the storyboard ID in its payload with the key identifier

4. Check for the ID in application:didFinishLaunchingWithOptions: by adding the following at the end of the function:

if let payload = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary, identifier = payload["identifier"] as? String {
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier(identifier)
    window?.rootViewController = vc
}
