If I don't use shared_preferences it will succeed

@cbracken: Could this be because a pod step failed?

This sounds like pod install may have failed.

@katout, would you mind attaching the output of flutter -v build ios?

Assuming that fails, what happens if you run flutter -v run with an iOS device attached?

Thank you for reply! @chinmaygarde and @cbracken.
I think so too. The cause is cocoapods.

flutter -v build ios

notConnect.txt

flutter -v run (with an iOS device attached)

this case, success!
connect.txt

found a solution

1. open ios/Runner.xcodeproj
2. I checked Runner/Pods is empty in Xcode sidebar.
3. drop Pods/Pods.xcodeproj into Runner/Pods.
4. "Valid architectures" to only "arm64" (I removed armv7 armv7s) Error building ios archive in xcode #13364

@katout thanks for the update.

For what it's worth, as of the latest dev branch release, you should be able to safely set the architectures to the default value. Flutter should now be able to detect the change to the project and run the appropriate pod steps. I expect this should make it to the beta branch within a week.

I think so too. The cause is cocoapods.

flutter -v build ios

flutter -v run (with an iOS device attached)

Solved! tks u really helped me !! :)

I figured out the problem, all of the deployment targets need to be the same. That is, in the project file, the target, and the pods project as well.

This is always reproducible.
I even created a new project, just pasting this dependency causes Archive problem.
Build for a physical device or Generic device works fine.
