My method takes a val requestSystemPhotoLibraryAccessPermission: suspend () -> SystemPhotoLibraryAccessLevel suspend lambda. What is the correct way to call this in Swift?

requestSystemPhotoLibraryAccessPermission: {} gives me an error as soon as I add the suspend keyword: Argument type '() -> ()' does not conform to expected type 'KotlinSuspendFunction0'

What do I need to change?
I don't understand that from the docs. 🙈

Its not possible

That explains a lot 😄

Here is something about a similar request, mapping it to `() -> Void async`: https://youtrack.jetbrains.com/issue/KT-48774

As a workaround, I use some wrapper in iosMain which takes a non suspend lambda

Thank you.

Will a Flow also work?

Thank you! 🙂

Can you share an example of your wrapper to a non suspend lambda @hfhbd ? Did you notice some downside/limitation of this approach?
