Answer 1

My setup: VS Code, Flutter

If you don't have Podfile.lock file and pod update doesn't help, try this:

1. Go to ios/Pods/Local Podspecs directory in your project
2. Check every json file to find highest required ios version. Mine was "ios": "10.0" in some of them
3. Go back to ios/ directory
4. Open Podfile file
5. Uncomment # platform :ios, '9.0' and replace 9.0 with version from 2. step, for example 10.0.
   • # platform :ios, '9.0' > platform :ios, '10.0'
6. Run pod install and the error should be gone

Answer 2

pod update 

Should do the trick. You're welcome :-)
