Ios 10 - Changes in Asking Permissions of Camera, Microphone and Photo Library Causing Application to Crash

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

[UPDATED privacy keys list to iOS 13 - see below]

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 (iOS 6, iOS 7), but since iOS 10 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:

Source

Alternatively, you can open Info.plist as source code:

And add privacy keys like this:

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

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.

iOS app does not ask camera and microphone permissions on TestFlight?

To make sure your app has permission before capturing media, follow the steps below.

Configure Your App's Info.plist File

iOS requires that your app provide static messages to display to the user when the system asks for camera or microphone permission:

• If your app uses device cameras, include the Privacy - Camera Usage
  Description key in your app’s Info.plist file.
• If your app uses device photo library, include the Privacy - Photo
  Library Usage Description key in your app’s Info.plist file

Verify and Request Authorization for Capture

You can add below code in AppDelegate main file OR while click on capture media to request access authorization.

import AVFoundation

AVCaptureDevice.requestAccess(for: .video) { granted in

            if granted {
            // Setup your code.
            }
        }

Using device CAMERA ON IOS 10 causes the application to be terminated

I Solved This issue:-
Go to info.plist - Your Xcode bundle
Click the "+" and go down the resulting list until you see "Privacy - Camera Usage Description". Add this item to by clicking it inside that list.

Format
..-Info.Plist
Key :- Privacy - Camera Usage Description
Type :- string
Value :- empty - Don't enter anything

Just clean xcode project and run it ... it's worked for me.

Apple store demands audio permissions in {mediaType: 'photo'}

The microphone permissions probably would be demanded because from mediaType 'Photo' the user could access to the video recorder witch could record audio too ( a video is a mix of photo and audio ).

Request Permission for Camera and Library in iOS 10 - Info.plist

You have to add the below permission in Info.plist. More Referance

Camera :

Key       :  Privacy - Camera Usage Description   
Value     :  $(PRODUCT_NAME) camera use

Photo :

Key       :  Privacy - Photo Library Usage Description    
Value     :  $(PRODUCT_NAME) photo use

iOS10 UIImageWriteToSavedPhotosAlbum TCC__CRASHING_DUE_TO_PRIVACY_VIOLATION

You can save any UIImage to the photo album but first you must ask the user for permission to do as this as it is indeed a privacy issue. If they don't give you access then you can't save the image at all.

The most sensible approach is to add the required privacy key to the info.plist.

This is the info.plist xml definition although it's easier to add the keys in the property list:

<key>NSPhotoLibraryAddUsageDescription</key>
<string>Message requesting the ability to add to the photo library</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Message requestion the ability to access the photo library</string>

If you add these then when you first try to access or add to the photo library a popup will display with your message allowing the user to decide if they want your app to have access.

One good reason to put it in the info.plist file is that all the requests for access are then in a single easily visible place instead of somewhere random in your project.

EDIT

Here is how to save the image in documents which does not raise and privacy issues:

NSData *imageData = UIImagePNGRepresentation(image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:@"image.png"]; //Add the file name
[imageData writeToFile:filePath atomically:YES]; //Write the file

If you want a jpg instead of a png use this instead:

NSData *imageData = UIImageJPEGRepresentation(image, 0.9); // Use whatever compression ratio you want instead of 0.9
