Continious Info.plist must contain an NSCameraUsageDescription key

I keep trying to run my app on through my phone, and when it comes to point when i press the open camera button i this error:

This app has crashed because it attempted to access privacy-sensitive data without a usage description.  The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

(lldb) 

I have cleaned the project and the build directory along with deleting the derived data folder and restarted x-code. I have the key in my p.list and a string with the description. I dont know what the issue is.
