Crash on session.addOutput(self.captureVideoOutput) about cameraengine HOT 3 CLOSED

+1. I'm getting this, too.

I think I've figured out what was causing this issue for me. Hopefully this will help you also.

I ended up needing to add Microphone permissions to my info.plist

<key>NSMicrophoneUsageDescription</key>
<string>Place whatever description you want here</string>

While you're at it, it might be helpful to add these permissions as well.

<key>NSCameraUsageDescription</key>
<string>Your description</string>

<key>NSPhotoLibraryUsageDescription</key>
<string>Your description</string>

My app doesn't use video capabilities, so I never thought to add the microphone permissions. However, when CameraEngine is initialized and it starts adding these Outputs, Xcode will crash if you aren't asking permission to use certain parts of the hardware.

Xcode really does a bad job of handling these errors. So, it doesn't seem like it has anything to do with CameraEngine at all.

remirobert: It might be helpful to future users if you place a warning in the README file about these required permissions in iOS 10. Just a thought. Thanks for all your hard work on this.

@natewitty That was it. I'm assuming this is documented somewhere by Apple, so it was my fault for not RTFM, but Xcode could definitely do a better job of handling this. Time to file a radar...
