Onesignal-flutter-sdk: ld: framework not found FirebaseCore

[FabianVarela]

Hi there

I have an error when try to execute my app in iOS phone or simulator.

I followed the instructions with the page (https://documentation.onesignal.com/docs/flutter-sdk-setup). But the error persists.

Also, I clean, build, set the commands pod Install, Pod deintegrate, delete Pod folder, PodFile.lockfile, delete files in ~/Library/Developer/Xcode/DerivedData, delete Target OneSignalNotificationServiceExtension and create it again. But the error continues.

I'm using the package onesignal_flutter: ^2.2.0

Thanks

@FabianVarela The OneSignalNotificationServiceExtension target should only have OneSignal as a dependency, make sure you don't have any other pods in your Podfile for this target.

Hi @jkasten2 actually this is my PodFile

I need set use_frameworks! in OneSignalNotificationServiceExtension target, because appears this error

Runner (true) and OneSignalNotificationServiceExtension (false) do not both set use_frameworks!

Uncomment this line to define a global platform for your project

platform :ios, '10.0'

Even I faced the issue, but i resolved it. I am still not sure is this the right way to do it or not. But i will share you the solution which i have done by looking into stackoverflow.

Open your project (ios directory) in xcode.

Navigate to One signal extension and in that General Tab.

Search for Linked Frameworks and add the Firebase Core Framework by tapping on the + icon and try to build it (if your project is using Firebase core.).

[FabianVarela]

Hi @GadepalliAditya1998, I did made the steps that you recommended:

• Select the OneSignalNotificationExtensions

• Added the FirebaseCore Library

• Clean and Build from XCode, but the error persists

@FabianVarela Texted on facebook can you just reply there?

[FabianVarela]

Perhaps changing the Embed setting would do the trick?

[FabianVarela]

@rgomezp can you help me where I change the embed setting, what are the steps? Thanks

[rgomezp]

@FabianVarela ,
Next to the framework, the current setting is "Do Not Embed". Try toggling that

[rgomezp]

Take a look at my response here

Closing due to no response

[FabianVarela]

Hi @rgomezp the solution that one signal support did give to me is with this link:
https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/42#issuecomment-459476383

Moreover, I had to change my project from objective C to swift, add or link all the packages to OneSignalNotificationExtensions

And the error has gone

Thanks

[FabianVarela]

Can I recommend, update the documentation in OneSignal Flutter SDK or create a troubleshotting?

Thanks
