Hello! I would like to take advantage of the callAsFunction operator in Swift like the operator fun invoke function in Kotlin. I tested its feasibility and by using @ObjCName("callAsFunction") I’m able to achieve that behavior.
Is there a way to declare an annotation that applies the ObjCName renaming to the annotated function? I thought that this would have worked but it didn’t…

@OptIn(ExperimentalObjCName::class)
@ObjCName("callAsFunction")
annotation class SwiftCallAsFunction

my goal is to avoid to repeat the "callAsFunction" string everywhere is needed. I thought about using a constant but I would like to understand if there are other ways

thanks!

No it won't work. You need a compiler plugin.
But keep it simple.

Maybe it's something that the folks at #touchlab-tools can help?

I’ll try to post it also in that channel, thanks
