How do you create a notification content extension without using a storyboard

Question

I want to create a Notification Content Extension to take advantage of the new iOS 10 rich notifications. However, in the main application we do not make use of interface builder. How can I create a content extension that does not utilize a story board?

Answer 1

1. Create the Notification Content extension target as you normally would.

2. Remove the storyboard file from the project

3. Remove the NSExtensionMainStoryboard entry from the extension's Info.plist.

4. Add a new entry of NSExtensionPrincipalClass to the Info.plist under NSExtension . The value should be the namespace of your extension and the class of the main ViewController. For example, if your extension is called Pretty Notification and the class is PrettyNotificationViewController , you would enter Pretty_Notification.PrettyNotificationViewController .

Note: Your principal class must conform to UNNotificationContentExtension
