Xcode – React Native iOS build fails – Mac M1

I created a react-native project and added Firebase libraries to it. After which when i try npx react-native run-ios the build fails with below message.

CompileSwift normal x86_64 (in target 'ExpoModulesCore' from project 'Pods')
        CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler (in target 'ExpoModulesCore' from project 'Pods')

I tried pod clean and pod install, pod deintegrate etc. Cleaned the xcode rm -rf ~/Library/Developer/Xcode/DerivedData Nothing works, my React Native version 0.64.3

Restarted my laptop as well 🙂
