AVSpeechSynthetizer.WriteUtteranceAsync crash

[prollin]

Steps to Reproduce

1. Call AVSpeechSynthetizer.WriteUtteranceAsync

Expected Behavior

AVSpeechSynthetizer.WriteUtteranceAsync doesn't make sense since bufferCallBack gets called multiple time (the utterance data is provided in chunks)
To implement an async method that complete once the utterance is finished, AVSpeechSyntetizer.DidFinishSpeechUtterance needs to be used though it is probably better to let developers deal with this and only explose AVSpeechSynthetizer.WriteUtterance API (which should already be async)

Actual Behavior

Crash when calling AVSpeechSynthetizer.WriteUtteranceAsync
