title: Fabric.io implementation (AppDelegate)
body: <p>I'm trying to implement Fabric into my app. The problem is, that the app isn't working correctly and I have no idea what code to place in my AppDelegate. I can't find any information on the web what should I implement there. Can anyone give me a tip, what functions should I implement in my AppDelegate?</p>
