Swift offers the possibility to omit argument names when calling a function if the function is declared like

func foo(_ arg: Bar) {}

. I.e., you can just

foo(myArg)

instead of having to

foo(arg: myArg)

It’s probably not possible to declare a function in kotlin that behaves the same way at the swift callsite, right?

The only scenario I'm aware of where you can do this is extension functions which (assuming they don't come through as Swift extensions) end up looking like

func foo(_ receiver: Bar)

Kotlin interoperates with Objective-C, so I suppose this could theoretically be possible by tweaking the Objective-C signature. I don't think it's possible in Kotlin/Native now, though.

Yeah they could definitely add an annotation or something to control this, but it doesn't exist now. Just like the lack of

@JvmName

and

@JvmOverloads

analogs in native
