Fix Ionic/Cordova App iOS 10 NSCameraUsageDescription Permission



Read on for an easy three step solution:

Our Ionic app makes use of the internal camera to scan barcodes and QR codes on vouchers we sell. Since iOS 10, Xcode urges app developers to provide a reason (NSCameraUsageDescription), why your app needs the permission to access the camera or photo library. While you can still build the app and upload it to the app store, it will be rejected with the following mail:

[…] This app attempts to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data. […]

The issue: NSCameraUsageDescription

Xcode 8 asks you to provide a key/value pair for NSCameraUsageDescription info.plist.

So if your Ionic/Cordova App uses the camera or photos library and you already got the same rejection mail when you uploaded the newest build, here’s the 3-steps solution:

1. Remove the “offending” plugin

We will re-install it later, but first we have to remove the plugin. In our app the phonegap-plugin-barcodescanner plugin caused the problem (you can always get a full list of all installed plugins with the command cordova plugin list).

Open your console (CMD on Windows, Terminal on OS X), right-click-paste the following line and hit enter:

cordova plugin rm phonegap-plugin-barcodescanner

The command tells cordova to remove the plugin “phonegap-plugin-barcodescanner” from all of your installed platforms.

2. Re-add the cordova plugin again

Now, re-add the plugin, this time with the attached variable CAMERA_USAGE_DESCRIPTION. If you want to install a specific version of the plugin, in our example version 4.1.0., attach @4.1.0 to the plugin name:

Install the latest version:
cordova plugin add phonegap-plugin-barcodescanner --variable CAMERA_USAGE_DESCRIPTION="Scan QR-Codes" --save

OR: Install a specific version
cordova plugin add phonegap-plugin-barcodescanner@4.1.0 --variable CAMERA_USAGE_DESCRIPTION="Scan QR-Codes" --save

Cordova re-installs the plugin and adds it to all installed plattforms. It will then add a new variable to the config.xml file by the name CAMERA_USAGE_DESCRIPTION and a value with a string of your choice explaining why your app needs camera access:

<plugin name="phonegap-plugin-barcodescanner" spec="~4.1.0">
<variable name="CAMERA_USAGE_DESCRIPTION" value="Scan QR-Codes" />

3. Re-build your App for iOS

Now run the following code in your Terminal to rebuild your iOS app:
ionic build ios --release

Then open your Apps .xcodeproj-file in Xcode. It’s located under your apps main folder in “platforms/ios/NAME-OF-YOUR-APP/NAME-OF-YOUR-APP.xcodeproj”. Select the “Generic iOS Device”, click “Product > Archive” and upload your error-free Build.

  1. Thanks for the tips, but I’m still having trouble with the barcodescanner. When I call the scanner from my app, nothing happens until I click the home key, and tap on the app icon again, then I get the scanner window. If I click on “cancel” the barcodescanner closes ok. If I click on my apps scan button again, I have to go back to the iOS home screen and tap on the app icon again to get to the scan window. If I tap on my apps scan button twice, I get a “Scan is already in progress.”, so it looks like the handler is working. Anybody have any ideas?


  2. I have done all three steps and I’m still having the same error. App crashes because it lacks that description. I’m building it for debug… and running in an iOS 10 device.
    Any other hints?
