Declaring usage access to Microphone for privacy settings in info.plist iOS 10

Question

In my project i am using a hardware that uses the headphone jack to connect to the device and used to swipe card. Do i need to declare the usage access for microphone in info.plist?

My problem is few of my users reporting that the application crashes after login. from the below crash log i suspect that the related to an issue in accessing the privacy settings(i am not sure though). Please check the crash log as well and guide me on how to solve this issue.

I think you have to use UISupportedExternalAccessoryProtocols permission for user external hardware.

<key>UISupportedExternalAccessoryProtocols</key>
    <array>
        <string>PROTOCOL_NAME_HERE</string>
    </array>

PROTOCOL_NAME_HERE is bundle identifier of your protocol/external accessory.

And you have to add ExternalAccessory.framework in your project (Click on your project in the Project Navigator on the left side. In General go to "Linked Frameworks and Libraries". Click on the + button).
