NSCameraUsageDescription in iOS 10.0 runtime crash?

Using iOS 10.0 last beta. I had tried to use Camera to scan barcode in my app, and it crashed with this runtime error.

> This app has crashed because it attempted 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.

Put this key into the plist, but it still crashed?

After iOS 10 you have to define and provide a usage description of all the system’s privacy-sensitive data accessed by your app in Info.plist as below:

Calendar

Key    :  Privacy - Calendars Usage Description    
Value  :  $(PRODUCT_NAME) calendar events

Reminder :

Key    :   Privacy - Reminders Usage Description    
Value  :   $(PRODUCT_NAME) reminder use

You can get detailed information in this link.

As Apple has changed how you can access any user private data types in iOS 10.

You need to add the "Privacy - Camera usage description" key to your app’s Info.plist and their usage information which is apply for your application, as in below example I had provided that I have used to scan barcodes.

For more information please find the below screenshot.

You have to add this below key in info.plist.

NSCameraUsageDescription Or Privacy - Camera usage description

And add description of usage.

Detailed screenshots are available in this link

Alternatively open Info.plist as source code and add this:

<key>NSCameraUsageDescription</key>
<string>Camera usage description</string>

Use these raw values and copy in info.plist

    <key>NSCalendarsUsageDescription</key>
	  <string>$(PRODUCT_NAME) calendar events</string>
	<key>NSRemindersUsageDescription</key>
	  <string>$(PRODUCT_NAME) reminder use</string>
	<key>NSCameraUsageDescription</key>
	  <string>This app requires to access your photo library to show image on profile and send via chat</string>
	<key>NSMicrophoneUsageDescription</key>
	  <string>This app requires to access your microphone to record video with your voice send via chat</string>
	<key>NSPhotoLibraryUsageDescription</key>
	  <string>This app requires to access your photo library to show image on profile and send via chat</string>
	<key>NSContactsUsageDescription</key>
	   <string>$(PRODUCT_NAME) contact use</string>
	<key>NSLocationAlwaysUsageDescription</key>
	  <string>$(PRODUCT_NAME) location use</string>
	<key>NSLocationWhenInUseUsageDescription</key>
	  <string>$(PRODUCT_NAME) location use</string>

the xcode UI has changed a bit from one version to the next so here is where you update the plist for 9.0 beta 4 if it helps Project ->Target ->Info

If you're using Ionic, you can solve it directly from config.xml by adding inside platform ios tag:

<platform name="ios">
.
.
.
    <config-file target="*-Info.plist" parent="NSPhotoLibraryUsageDescription">
        <string>photo library usage description</string>
    </config-file>
    <config-file target="*-Info.plist" parent="NSCameraUsageDescription">
        <string>camera usage description</string>
    </config-file>
.
.
.
</platform>

I'd like to thank @BHUPI answer too.

For those who are still getting the error even though you added proper keys into Info.plist:

Make sure you are adding the key into correct Info.plist. Newer version of xCode, apparently has 3 Info.plist.

One is under folder with your app's name which solved problem for me.

Second is under YourappnameTests and third one is under YourappnameUITests.

Hope it helps.

Another instance that I faced while trying to use the camera, was that it was still busy crashing giving same _CRASHING_DUE_TO_PRIVACY even after adding the "Camera Usage Description". After failing to get anything tangible from the call stack, switched to the "Organizer" and looked into the crash reports on the device. I found that it was in fact complaining about the privacy due to the missing "Microphone Usage Description". I added that and got rid of such a cryptic break down.

I checked the plist and found it is not working, only in the "project" info, you need to add the "Privacy - Camera ....", then it should work. Hope to help you.

You do this by adding a usage key to your app’s Info.plist together with a purpose string. NSCameraUsageDescription Specifies the reason for your app to access the device’s camera

I had the same problem and could not find a solution. Mark90 is right there are a lot info.plist files and you should edit the correct. Go to Project, under TARGETS select the project (not the tests), in the tab bar select Info and add the permission under "Custom iOS Target Properties".

For those that like myself are testing an Ionic project and have to add privacy permission keys, make sure you add them in the right .plist file. The best way to find it is to use Xcode search, the one with your app name is the one. I share a screenshot with a circle around the right Info.plist you need to modify. I had lost time modifying the other one in the library folder and resulted in errors about privacy. Hope this screenshot helps. In my case at the bottom of the file I clicked on + and scrolled until I found Privacy - Camera usage description, I inserted the short description used for Qrcodes and worked
