The majority of iOS example apps won't work on the simulator (because you don't have a camera there, you know...). Try the example on real iOS device ;) gl

Hi. On iOS 10 you can have issues because of new permission policy. As far as i understand this repo have no updates in info.plist. Zubco's repo has it so you can try his fork

@dvma04 I have opened a PR 3 days ago, waiting for @BradLarson review.

dd-ios commented 7 years ago

@zubco i know this. i've left you a comment on yours PR, cause you missed microphone permissions in info.plist. Please review if it make sense. Maybe you need to update it.
