+#### Wrap the UnityAppController into your application delegate
+
+We are taking away control from the unity generated application delegate, we
+need to act as a proxy for it in our `AppDelegate`.
+
+First add the following variable to your `AppDelegate`
+
+```swift
+var currentUnityController: UnityAppController!
+```
+Now we need to initialize and proxy through the calls to the `UnityAppController`.
+All said and done you will be left with the following:
