Onesignal-flutter-sdk: 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

bash 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

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!

@thedude61636 this issue has been discussed (extensively). If you use use_frameworks! in your Podfile, our SDK simply will not work - there is currently no way around this unfortunately. Please see #21 for more detail.

[Nightsd01]

@Allan-Nava Really...? Please post your Podfile.....

[thedude61636]

@Nightsd01 okay, noted.
does downloading the sdk directly from the repo work? because as far as i understand the issue is with cocoa
I'm new to ios so please bare with me

[Nightsd01]

@thedude61636 the problem is that our Flutter SDK depends on our native iOS SDK, so it’s not a direct dependency. If you can figure out a way to do it I’d love to hear it.

[lifenautjoe]

Hi everyone. I fixed it with help of @smjcdowall.

It's a work-around and I hope a temporal one.

The steps are here https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/42#issuecomment-459473364 .

Cheers.

I used the same pod @thedude61636

[Nightsd01]

@Allan-Nava if you are using the same Podfile as @thedude61636 then the comment I posted for him would apply in your case as well. Our framework is not compatible with use_frameworks! at the moment...

[Allan-Nava]

Ok tomorrow I will try

@lifenautjoe when I use your PodFile I got this error:

@Allan-Nava you have to remove use_framework! from the podfile

I had the error bellow

I've linked all missed libraries and this fixed the error:

Thanks to this comment

[vmwsree]

@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

How do you remove app extention

[rgomezp]

I'm closing this issue as it is a duplicate of #42 . You can follow any updates on the issue there.

Any Update?
Thx A lot

I was able to fix this issue by following the steps here:
https://github.com/Baseflow/flutter-geolocator/issues/168

I had to update information in the pod file.
It is when you have links in your app to open in safari, it seems Apple made changes so when you run build through Xcode it is requiring the policy updates and minimum requirements are met. Part of it I think is you can not run an older swift version aimed at ios 9.0 on a version you may set as 11.0
