NSPhotoLibraryUsageDescription key must be present in Info.plist to use camera roll

Recently I started to get this error:

> NSPhotoLibraryUsageDescription key must be present in Info.plist to > use camera roll.

I am using React Native to build my app (I am not familiar with ios native development) and I don't know how to add this key to Info.plist

Can you post an example? Thanks

I am using npm package "react-native-camera-roll-picker": "^1.1.7"

Thanks @rmaddy, I added this just after other key-string pairs in Info.plist and fixed the problem:

<key>NSPhotoLibraryUsageDescription</key>
<string>Photo Library Access Warning</string>

Edit:

I also ended up having similar problems on different components of my app. Ended up adding all these keys so far (after updating to Xcode8/iOS10):

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>

MY FAVORITE WAY TO DO IT

1. Open info.plist

2. Click this button to add a new key

3. Scroll down to find Privacy - Photo Library Usage Description

4. Select it, then add your description on the right

Add following code in info.plist file

<key>NSPhotoLibraryUsageDescription</key>
<string>My description about why I need this capability</string>

You need to paste these two in your info.plist, The only way that worked in iOS 11 for me.

    <key>NSPhotoLibraryUsageDescription</key>
    <string>This app requires access to the photo library.</string>
    
    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>This app requires access to the photo library.</string>

As of now August 2021, not only we have to add this :

<key>NSPhotoLibraryUsageDescription</key> 
<string>We need access to photo library so that photos can be selected</string>

but also need to add this to info.plist file inside iOS folder in order to work properly

<key>NSPhotoLibraryAddUsageDescription</key> 	
<string>This app requires access to the photo library.</string>

For camera access use:

<key>NSCameraUsageDescription</key>
<string>Camera Access Warning</string>

i faced the same issue few days earlier for my IONIC 4 Project. when i uploaded my IPA, i got this warnings from App Store Connect.

I fixed the "Missing Purpose String in info.plist" issue, by the following steps. hope it will also work for you.

1. Goto your "info.plist" file.

2. Find this key, called Privacy - Photo Library Usage Description. if it's not present there, add a new one and it's value, like below image.

Thanks.

In order to save or retrieve an image from the camera roll. Additionally, you need to ask the user for the permission otherwise you'll get this error or your app may get crashed. To save yourself from this add this into your info.plist

<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app requires read and write permission from the user.</string>

In the case of Xamarin.iOS

 if you're adding it from the generic editor then "Privacy - Photo Library Additions Usage Description" will be the given option you will find out instead of "NSPhotoLibraryAddUsageDescription".

If you added the key-string pairs in Info.plist (see Murat's answer above ) and still getting the error, try to check if the target you're currently working on has the keys.

In my case I had 2 targets (dev and development). I added the keys in the editor, but it only works for the main target and I was testing on development target. So I had to open XCode, click on the project > Info > Add the key-pair for the development target there.

When using NSCameraUsageDescription the user can access the camera AND select images from the photo library. So I don’t need NSPhotoLibraryUsageDescription, correct?

"Privacy - Photo Library Additions Usage Description" for iOS 11 and later

"Privacy - Photo Library Usage Description" for iOS 6.0 and later

Open plist file and this code

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app requires access to the photo library.</string>
