Error when building for iOS after following SDK setup tutorial

[lifenautjoe]

Head's up: It's not working for android either. See #56

Description:
After following every step, to the letter of the Official SDK Setup, when running

flutter build ios --release

The job fails with

I really have no clue what this might be.

Environment

• OneSignal Flutter SDK ^1.0.0 (As in the example)
• Flutter 1.0.0 • channel stable • https://github.com/flutter/flutter.git

Sorry about that.

This is what I get when I try to build on XCode

[lifenautjoe]

Hour 7 of breaking my head..

Reading through the iOS SDK Setup, I've noticed it's mentioned that after adding the service extension, the project must be always built from the xcode workspace, rather than the xcode project.

So I closed XCode, reopened the workspace file, hit build and it built successfully.

However...

From flutter commands such as flutter run or flutter build, it fails with errors related to not being able to locate directories.

My best bet is that flutter doesnt take into consideration the workspace mode and rather tries to build the project, therefore it fails (?)

Please, save me from having to use Firebase notifications 😢.

[lifenautjoe]

Update: Archiving the app from XCode does not work, only running it.

Errors are the same. Libraries not found.

[Nightsd01]

@lifenautjoe sorry you’ve spent so much time on this! Unfortunately Flutter uses Cocoapods in a rather......unique.....way, and this can lead to issues like this.

It appears you’re facing a similar issue to #42

Do you need badge count notifications, images, etc? If not, removing the extension service entirely should fix this for you.

If you do, unfortunately Flutter’s Cocoapods scripts don’t play nice with projects that have app extensions, there’s not much we can do. I would suggest creating an issue on the Flutter repo

[lifenautjoe]

Hi @Nightsd01 ,

Sorry to hear that... Don't really know where to start to explain this to the Flutter team. I have no expertise with iOS nor Cocoapods.

For now.. I guess no other choice but to use Firebase Messaging...

Cheers.

[Nightsd01]

@lifenautjoe if you intend to use rich push notifications with images you will likely run into the same issue with Firebase. The user in #42 found a workaround - I’d suggest starting there

[Nightsd01]

@lifenautjoe I would also suggest trying to run our example project. Do you run into the same problem there?

[lifenautjoe]

Alright, hoping on the person to shed some light into his solution.

Will try running the project tomorrow morning first hour.

Cheers for now and thanks for being around!

hi i'm having the same issue
this is my pod file, please notice that i added use_framework! to the OneSignalNotificationServiceExtension target as cocoa complained that i don't have both targets (runner and the extension) set to use it
