 <p>Starting from iOS 10, <strong>it's mandatory to add "NSCameraUsageDescription"</strong> in info.plist which is just an informatory message to the user stating the reason for accessing camera. It will be displayed to the user while trying to access the camera.</p> <p>Though this key is existing since iOS 7, it has been made mandatory in iOS 10 beta. Please refer to below Apple reference link.</p> <p><a href="https://developer.apple.com/library/prerelease/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW15" rel="nofollow">https://developer.apple.com/library/prerelease/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW15</a></p>
