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

[ivarli]

What happened?

I followed every step from Onesignal Flutter Tutorial, i am debugging since 3 days, but it still won't work. I tried out OneSignal on 16.09.2024 and it worked fine, but now after one Month nothing works. I can't start the app, because XCode is giving me the erorr that "Project 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. I tried almost every suggested ones... I also asked ChatGPT-o1, followed 15 Steps step by step and have no solution yet...

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 Tutorial 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.

Here the final error screenshot:

OneSignal Flutter SDK version

5.2.6

Which platform(s) are affected?

• [X] iOS
• [ ] Android

Hi @ivarli

The issue is resolved by simply removing OneSignalNotificationServiceExtension.appex from Framework, Libraries and Embedded content section

Before

After

[ivarli]

Thanks a lot, I had to flutter clean once more, after your solution and it worked. You saved me days of headaches.

[harrynguyenangle]

no, this will lead to another issue

[!] Unable to find host target(s) for OneSignalNotificationServiceExtension. Please add the host targets for the embedded targets to the Podfile.

How do i add host target. I followed the one of removing the file and as you say it then gives this error on podfiles. Thanks
