Troubleshooting

Before opening an issue, make sure you try the following:

iOS

  1. Try cleaning and rebuilding everything: 
    rm -rf package-lock.json && rm -rf yarn.lock && rm -rf node_modules && rm -rf ios/Podfile.lock && rm -rf ios/Pods
npm i  # or "yarn"
cd ios && pod repo update && pod update && pod install
  2. Check your minimum iOS version. react-native-vision-camera requires a minimum iOS version of 11.0. Try updating your Podfile iOS version at the top.
  3. Check your Swift version. react-native-vision-camera requires a minimum Swift version of 5.2. Try removing all references to Swift-5.0 in the LIBRARY_SEARCH_PATHS list (see this Stackoverflow answer)
  4. Make sure you have created a Swift bridging header in your project.
    1. Open your project with Xcode (Example.xcworkspace)
    2. In the menu-bar, press File > New > File (⌘ + N)
    3. Use whatever name you prefer, e.g. File.swift, and press Create
    4. Press Create Bridging Header when promted.
  5. If you're experiencing weird behaviour, check the logs in Xcode to find out more.

Android

  1. Since the Android implementation uses the not-yet fully stable CameraX API, make sure you've browsed the CameraX issue tracker to find out if your issue is a limitation by the CameraX library even I cannot get around.
  2. If you're experiencing weird behaviour, check the logs in Android Studio/Logcat (⌘ + 6) to find out more.
  3. If a camera device is not being returned by getAvailableCameraDevices(), make sure it meets the minimum requirements - that is minum supported harwdware level of LIMITED and above. See this section in the Android docs for more information.
