'react_native_geolocation_service.modulemap' not found

Faced this issue today, running on a M1 Mac, react-native@0.67.2 and react-native-geolocation-service@5.2.0. Doing as @rossjohnsonMP said fixed it. Already had platform :ios, ‘11.0’ set on Podfile, but there were still some references to 10.0 on XCode files. On XCode, I selected the target I wanted on the project navigator, then Build Settings > Deployment > IOS Deployment Target > Changed it to 11.0, boom, it worked

If it helps anyone, I had the same problem and I got it to build by adding ‘arm64’ to ‘Excluded Architectures’ under Build Settings, both in the main project and for the pod. I’m using react-native 0.66.0, on M1-machine in Xcode 13.

Build settings for the app under Targets (setting it under Project didn’t seem to help):

Modified post_install in my Podfile. Since multiple pods were causing the ‘modulemap not found’-error, this makes sure all of them adds ‘arm64’ to ‘Excluded Architectures’:

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)

    # Added code below
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
      end
    end
  end

Run ‘pod install’

Note: I don’t know if it’s a good idea to apply these settings to pods where it’s not needed, but I haven’t noticed any issues.
