I am developing an app with request access to user’s microphone. It was working fine with iOS 9, but since upgrade to iOS 10, it terminates with error message shown in the terminal:

> 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.
> (lldb)

To solve the problem, edit the Info.plist file as source code and add the following:

    <string>Some microphone description whatever you want</string>

For your reference, in case you need access to user’s camera, use the follow:

    <string>Some kind of camera request description</string>

Or request for contacts access for your reference.

    <string>This app request access for your contacts</string>

Happy coding!
