Hello guys!
I have a doubt about implementing background tasks in kmm. In android we've used workmanager so far. How can we implement background tasks in kmm apps?

[Pablichjenkov]

Apple has a framework called BackgroundTask. You may find some similarities with Android Work Manager and create a wrapper layer around that

I actually just started working on a library to help with this. Currently only have a POC for in-process schedules and WorkManager, but iOS support is something I will be looking into as well. Still an early prototype, but feedback and/or contributions (especially for iOS) would be greatly appreciated! https://kotlinlang.slack.com/archives/C03GTEJ9Y3E/p1697648634102369

There are several KMP libraries I’ve seen that do “background tasks”, but from what I can tell, they all are just some form of “background threads” and don’t support persistent work like WorkManager.

BackgroundTask only works for iOS 13 and above though, so if you want to support earlier versions you'd want to use this.

[Pablichjenkov]

Isn't iOS 13 a bit outdated? How many existing devices are running that OS version. It is around 4 years old and the average phone last no more than 2 years. Especially iOS, that has a better new device adoption rate than Android.

[Casey Brooks]

Yeah, looks like 97% of iPhones are running iOS 13 or higher (source). Unless you have very specific needs to run on very old phones, a requirement of iOS 13 seems perfectly reasonable

[Aditya Kurkure]

interesting, I've had to work with apps targeting iOS 12 before and it was a bit of a hassle that's why I thought of mentioning it.

[Pablichjenkov]

Is a valid point, it depends on the project and the type of user you target obviously. Is a balance between ease of development using a newer API at the cost of losing a few users.
