No such module 'workmanager' error in AppDelegate.swift. When i use workmanager_apple instead of workmanager is fine. But when app is in background,
[workmanager_apple.BackgroundWorker] performBackgroundRequest(_:) -> performBackgroundRequest.failed
this error occurs. Is this new version error or i missed something?

@tharun797 @zolboo918 @ilyasarafathemvigo Looks like the module was renamed to workmanager_apple
After renaming it, everything worked.

@zolboo918 can you please share a reproducer/sample app - or a lot more details about the

[workmanager_apple.BackgroundWorker] performBackgroundRequest(_:) -> performBackgroundRequest.failed

error?

What are you returning in your dispatcher?

I'm stuck on this as well - if I switch it to workmanager_apple, it crashes and won't run.

What is the fix for this?

It is not a problem, send empty map as inputData.
