Termination Reason: TCC, This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data. Triggered by Thread: 1 I don't know what permissions i need to add.

Answer 1

iOS 10 onwards, when you access privacy sensitive resources like camera, microphone you should add usage description text to info.plist.

This text will be shown in alert asking user to grant permission to access the resource when your code tries to access the resource for the first time.

So you should put appropriate message explaining why your app needs the resource :)

Add key NSMicrophoneUsageDescription and a text description to info.plist and it will not crash again :)

Answer 2

Just add NSMicrophoneUsageDescription key & in value add the justification that why your app is using Microphone. This is the latest requirement in iOS 10.

Answer 3

只需在info plist中添加“NSMicrophoneUsageDescription”，即可从所需的麦克风访问私人数据。
