Dependency Service Sample does not work

I tried runnign the Dependency Service Sample and it falls short running on iOS 8.4, either on device or in simulator. Works fine on Android.

It seems there's a bug in iOS with the AVSpeechSynthesizer and some Objective-C devs have recommended a workaround which I tried porting to C#... to no avail!

Workaround is here : http://stackoverflow.com/questions/24197952/avspeechsynthesizer-with-ios8

• (AVSpeechUtterance *)utterance {
  if (!_utterance) {
  ...
  _utterance = [AVSpeechUtterance speechUtteranceWithString:@"hello world"];
  [_utterance setRate:0.2f];
  [_utterance setVoice:[AVSpeechSynthesisVoice voiceWithLanguage:language]];

  // iOS 8 bug fix
  AVSpeechUtterance *dummyUtterance = [AVSpeechUtterance speechUtteranceWithString:@" "];
  [dummyUtterance setVoice:[AVSpeechSynthesisVoice voiceWithLanguage:language]];
  [self.synthesizer speakUtterance:dummyUtterance];
  

  }
  return _utterance;
  }

Anyone tried this sample on current iOS and make it work ? Would be a great demo to actually implemented this as a platform specific pre-requesite on iOS!
