[Bug]: OneSignalNotificationServiceExtension.appex is missing its bundle executable

[Deecency]

What happened?

I followed the step one Onesignal Flutter docs, I tried out the sdk and it works well on android but and nothing works on IOS. I can't start the app, because Xcode is giving me the erorr that "X can't be installed". I reproduced every step so many times, and got through all of stackoverflow and github issues about this error, but still can't find any solution.

Steps to reproduce?

1. Create a new Flutter Project
2. Pub add latest Onesignal flutter package.
3. Follow all the instructions exactly one to one in the Docs of Onesignal for Flutter.
4. Get Errors, and fix them with the known "PBXGroup" and "objectVersion = 56" replacement.
5. Refactor Build Phases for the next error: so that "Embed Foundation Extensions" get exactly under Copy Bundle Resources.
6. Run the App. 
7. Get Xcode Error, even if flutter does not throw an error.

What did you expect to happen?

I expected the app to build and run with the onesignal flutter package installed. Works well on android but xcode shows the error (KFA)

OneSignal Flutter SDK version

3.24.3

Which platform(s) are affected?

• iOS
• Android
