Swift 4 - The app's Info.plist must contain an NSCameraUsageDescription key

As of iOS 10, some features require an entry in the Info.plist before access will be allowed. This is for privacy purposes.

You can read more about this setting on Apple's developer website.

To solve this issue add the following to your Info.plist:

 <key>NSCameraUsageDescription</key>
 <string>[why you need camera access]</string>
