After upgrading BigSur to 11.3, Xcode to 12.5 and iOS to 14.5, I can’t run the iOS app on a real device nor in the simulator.

React-Native –>
react-native run-ios

kikirim@Levent-MacBook-Pro test % react-native run-ios
error Could not find "Podfile.lock" at /Users/kikirim/Desktop/React-Native/test/ios/Podfile.lock. Did you run "pod install" in iOS directory?

Use `sudo xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools, or use `xcode-select --install` to install the standalone command line developer tools.

error Could not get the simulator list from Xcode. Please open Xcode and try running project directly from there to resolve the remaining issues.
