yarn bundle:ios script translates to:

"bundle:ios": "react-native bundle --entry-file='index.js' --bundle-output='./ios/MyNewApp/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'"

/Users/runner/work/1/s/ios/MyNewApp/AppDelegate.h:1:9: 'RCTAppDelegate.h' file not found

To solve this issue, we need to set the .xcworkspace file instead of .xcodeproj file in the Xcode task -> xcWorkspacePath field.

For example:

- task: Xcode@5
  inputs:
    actions: 'build'
    sdk: 'iphonesimulator' 
    scheme: 'MyNewApp'
    packageApp: true
    signingOption: 'manual'
    provisioningProfileName: 'fr2024ProvisioningV1'
    configuration: 'Release'
    xcWorkspacePath: 'ios/MyNewApp.xcworkspace'
    exportPath: 'output'
    destinationPlatformOption: default
