Extension in iOS8 - Terminating since there is no system app

问题

Trying to run my iOS widget that is a "Today" extension. Every time i try to add it to the notification center, i keep getting the message "Terminating since there is no System App

Any ideas on how to fix this?

Im trying to make an extension that has a tableview in it

回答1:

In your project settings look for a setting that says "Launch Screen File" and remove anything so it is blank then clean and build.

I was having the same problem - Are you using swift? Commenting out the "init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?)" function as suggested in this response fixed it for me: iOS 8 Beta Today extension widget not showing in a Swift app?

I ran in to this issue with Swift in Xcode 6 - Beta 5. The error just seemed to appear randomly, and restarting Xcode fixed it.
