Answer 1

The above answer (by Rhythmic Fistman) is correct if your app is not compatible with iOS 9 or below.

If your app is compatible with iOS 9 you will see the next error:

'setCategory' is unavailable in Swift

In that case there is a bug with Swift 4.2, this is an issue with AVFoundation in Xcode 10's SDKs, you can work around it by writing an Objective-C function that calls through to the old API, since they're still available in Objective-C.
