This might be a firebase_core issue, but the logs still asked to create an issue.

@alex-medinsh

@alex-medinsh Thanks for reporting this issue! Could you please share a sample GitHub repository that I can clone to reproduce the issue on my end?

@puneetkukreja98 I am currently unable to reproduce this on a fresh project, but this issue happens on two separate projects which both use firebase_core, so my guess would be that this should be a project created with some previous version of Flutter for this issue to happen?
Any ideas what I can try to pinpoint the problem?

@alex-medinsh

@alex-medinsh Go to the Pod-file and try changing the platform version to 15; firebase_core requires a minimum platform version of 15.

It is already set to 15, since this is not a new project and already builds ok with Cocoapods. The issue happens when I enable SPM and the run command tries to migrate the project.

Routing this to team-ios for further investigation.

I was able to successfully build one of the projects. I killed all of the dart and flutter related processes, then ran flutter clean and then flutter build ios. The project was migrated to SwiftPM and then built.

I ran flutter clean multiple times before that and it didn't help, but killing the processes resolved the issue. Can this be related to the way Flutter now fetches SwiftPM dependencies with a separate background process? Maybe the process got stuck or left some caches in a broken state.

I still haven't ran flutter clean in the second project, so that we can use it to try to reproduce the issue.

@alex-medinsh Can you please provide your pubspec.lock? :)

Hi @LouiseHsu! I've attached the lockfile.

The separate background process was reverted, so hopefully this is fixed.

I'm going to optimistically close this, but if you see this pop up again, please file another issue.
