This is how I got react-native to compile on Apple Silicon without rosetta.

$ pod cache clean --all
$ yarn cache clean
$ rm -rf ~/Library/Developer/Xcode/DerivedData/*

$ npx [email protected] init MyApp
$ cd MyApp
$ open ios/MyApp.xcworkspace

(Make sure to be working in the .xcworkspace not the .xcodeproj)

Should look like this when you're done:

• File -> New -> File...
• Call it "BridgingFile.swift"
• Choose "Create Bridging Header"
• (File can remain empty)

Change the platform line to:

platform :ios, '12.1'

Replace use_flipper!() and post_install (lines 24-28) with:

  use_flipper!({ 'Flipper' => '0.95.0', 'Flipper-Folly' => '2.6.7', 'Flipper-DoubleConversion' => '3.1.7' })
  post_install do |installer|
    installer.pods_project.build_configurations.each do |config|
      config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.1'
    end
    react_native_post_install(installer)
  end

$ cd ios
$ rm -rf Pods Podfile.lock
$ rm -rf ~/Library/Developer/Xcode/DerivedData/*
$ pod deintegrate && pod setup && pod install

The XCode Project should now compile and run.
