NSCameraUsageDescription runtime crash in iOS 10.0 affects apps that attempt to access the camera without providing a clear explanation of their usage to the user.

This error can be frustrating for developers, as it requires additional setup and testing to resolve, but is essential for ensuring user privacy and compliance with Apple's guidelines.

⚠️ Common Causes

  • The NSCameraUsageDescription runtime crash occurs when an app attempts to access the camera without specifying a usage description in its Info.plist file. This is a security measure implemented by Apple to protect user privacy.
  • Alternative reason: In some cases, the crash may also be caused by a mismatch between the iOS version and the app's compatibility settings, or by a corrupted Info.plist file.

✅ Best Solutions to Fix It

Adding NSCameraUsageDescription to Info.plist

  1. Step 1: Open the project in Xcode and navigate to the project navigator.
  2. Step 2: Select the target that contains the app code and click on the 'Info' tab in the top-right corner of the window.
  3. Step 3: Scroll down to the 'Privacy - Camera Usage Description' section and click the '+' button to add a new key-value pair.
  4. Step 4: Enter a clear and concise explanation of how your app uses the camera, such as 'This app uses the camera to scan barcodes.'
  5. Step 5: Save the changes and rebuild the project to test for success.

Using a Camera Permission in Swift

  1. Step 1: Import the 'AVFoundation' framework in your Swift code by adding the following line at the top of your file: `import AVFoundation`.
  2. Step 2: Use the 'AVCaptureDevice' class to request access to the camera, like so: `let captureDevice = AVCaptureDevice.default(for: .video)`.
  3. Step 3: Check if permission has been granted using the 'AVCaptureDevice.requestAccess(to:)' method, and handle the result accordingly.

🎯 Final Words

By following these steps, you should be able to resolve the NSCameraUsageDescription runtime crash in your iOS 10.0 app and ensure that it complies with Apple's guidelines for accessing camera data.
