  • For react-native <= 0.59: Run \`react-native link react-native-device-info\` in the project root.
  • Rebuild and re-run the app.
  • If you are using CocoaPods on iOS, run \`pod install\` in the \`ios\` directory and then rebuild and re-run the app. You may also need to re-open Xcode to get the new pods.
  If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-device-info/react-native-device-info`);
