Answer 1

UIImagePicker

An image picker controller manages user interactions and delivers the results of those interactions to a delegate object. The role and appearance of an image picker controller depend on the source type you assign to it before you present it.

whenever you used UIImagePicker, you have to give permission for that particular application

There is a list of all Cocoa Keys that you can specify in your Info.plist file:

https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html

(Xcode target -> Info -> Custom iOS Target Properties)

iOS already required permissions to access microphone, camera, and media library earlier (iOS6, iOS7), but since iOS10 the apps will crash if you don't provide the description why you are asking for the permission.

Answer 2

You only have to add this key-value pair to your info.plist if you are actually accessing the photos any way. If it's not added the app is going to crash. Check if any of your added dependencies using UIImagePicker.

Answer 3

No it's not mandatory to add NSPhotoLibraryUsageDescription key in info.plist . If your App is not using accessing photo from library/gallery then you should remove it. But as "@Bence Pattogato" said if Your app accessing photo from library/gallery and there is no key added in info.plist then it will be crash.

For your information below are different keys that required to add info.plist if you accessing relevant features according to camera/photo library.

1) NSPhotoLibraryUsageDescription : This key lets you describe the reason your app accesses the user's photo library. When the system prompts the user to allow access, this string is displayed as part of the alert.

2) NSCameraUsageDescription : describes the reason that the app (including an iMessage app) accesses the device's camera. When the system prompts the user to allow access, this string is displayed as part of the alert.

3) NSPhotoLibraryAddUsageDescription : (New in iOS 11) This key lets you describe the reason your app seeks write-only access to the user's photo library. When the system prompts the user to allow access, this string is displayed as part of the alert.
