Can I pass a function

(UIBackgroundFetchResult) -> void

from swift to Kotlin? Currently the method I have written in kotlin expects a

(UIKUIBackgroundFetchResult) -> void

when called from swift.

I did a quick test, and yes you can do that. I had a function like:

fun doSomething(with: String, completion: (Time) -> Void) { }

And it was callable from Swift code without problem

Thanks. I still have the problem of swift expecting a

UIKUIBackgroundFetchResult

instead of UIBackGroundFetchResult though.

Oh I see… sorry I didn’t understand the question 😅 My bad. So on the Swift side it’s called

UIBackgroundFetchResult

but KMM translate it to

UIKUIBackgroundFetchResult

🤔 Hum… considering they are basically the same but with different names, I would cast the UIKUI version to UI. But this would need to be done on the Swift side.

Just tried this. Unfortunately it doesn't work.

Got the same issue. Did you get that sorted @Aditya Kurkure? I ended up returning result back to swift and handling it there, but that is not a perfect solution.

IOSFileKt.awaitResult { result in
            if result.isFailure {
                completionHandler(.failed)
            } else {
                completionHandler(.newData)
            }
        }

Yeah I did something similar. Haven't been able to find any other workaround.
