iOS 10-Changes in asking permissions of Camera, microphone and Photo Library causing application to crash (2)

iOS 10, Now Requires User Permission to Access Media Library, Photos, Camera and other Hardware like these. The solution for this is to add their keys into info.plist with a description for user that how we are using their data,

I could only find a few keys

NSPhotoLibraryUsageDescription
NSMicrophoneUsageDescription
NSCameraUsageDescription

I want to know if there are more keys also for other hardware as in iOS 10 if you haven't provided info.plist with proper keys description your application will crash if build using XCode - 8 beta.


Please find below codes for ios 10 request permission sample for info.plist .
You can modify for your custom message.

    <key>NSCameraUsageDescription</key>
    <string>${PRODUCT_NAME} Camera Usage</string>

    <key>NSBluetoothPeripheralUsageDescription</key>

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 app will crash if you don't provide the description why you are asking for the permission (it can't be empty).

Privacy keys with example description:

You can also open Info.plist as source code:

And add them like this:

<key>NSLocationAlwaysUsageDescription</key>
<string>${PRODUCT_NAME} always location use</string>

List of all privacy keys:

NSCameraUsageDescription
NSBluetoothPeripheralUsageDescription
NSCalendarsUsageDescription
NSContactsUsageDescription
NSHealthShareUsageDescription
NSHealthUpdateUsageDescription
NSHomeKitUsageDescription
NSLocationAlwaysUsageDescription
NSLocationUsageDescription
NSLocationWhenInUseUsageDescription
NSAppleMusicUsageDescription
NSMicrophoneUsageDescription
NSMotionUsageDescription
kTCCServiceMediaLibrary
NSPhotoLibraryUsageDescription
NSRemindersUsageDescription
NSSiriUsageDescription
NSSpeechRecognitionUsageDescription
NSVideoSubscriberAccountUsageDescription

Update 2019:

In the last months, two of my apps were rejected during the review because the camera usage description wasn't specifying what I do with taken photos.

I had to change the description from ${PRODUCT_NAME} need access to the camera to take a photo to ${PRODUCT_NAME} need access to the camera to update your avatar even though the app context was obvious (user tapped on the avatar).

It seems that Apple is now paying even more attention to the privacy usage descriptions and we should explain in details why we are asking for permission.
