It seems like there might be an issue with the Firebase Installations library on your iOS app. The error message you provided suggests that there was an issue copying a security item. Here are a few things you could try:
- Check if the Firebase Installations library is properly installed in your Xamarin.iOS project. You can do this by looking for the Firebase.iOS.Installations NuGet package in your project.
- Check if your Firebase iOS configuration is properly set up in your project. You can do this by following the Firebase iOS configuration instructions on the Firebase console.
- Check if there are any issues with the provisioning profile, certificate, or keychain access on your iOS device. You can do this by following the iOS code signing troubleshooting instructions on the Xamarin documentation.
