iOS Contacts Picker

So i was doing a tutorial from Sinch! on how to Fetch and Call Contacts,
Well it loads up the Contacts just fine.
The problem is that whenever I select a Contact to call, the app crashes and Xcode shows this error on the console.
Can anyone help me with that?

Answer

It says what happened at the very top

So figure out where you're calling something that utilizes an applicationKey and figure out why it's blank :)
