With kotlin/MPP 1.3.31 `fun foo(block: (Int) ->...

# multiplatform

[sunbreak]

With kotlin/MPP 1.3.31 fun foo(block: (Int) -> Unit) { ... } in Kotlin would be func foo(block: (KotlinInt) -> KotlinUnit) in Swfit, and foo(Function1<Integer, Unit> block) in Java.
Both require KotlinUnit.Init() (or Unit.INSTANCE)

After upgraded to 1.3.40, it can be func foo(block: (KotlinInt) -> Void) in Swift, without the KotlinUnit.Init().

Would it possible to omit the Unit.INSTANCE in Java?

it possible to omit the Unit.INSTANCE in Java

No, it’s not possible, because Such lambda represented by interface Function1<in P1, out R> on JVM, so you cannot declar R as Void.
