if I have a

fun args(args: Iterable<String>)

and i pass it an Array<String> it says array is not a subtype of iterable. What's the solution to this problem?

Several possibilities. 1 - Make

args

of type

Array<String>

. 2 - Pass something that is actually an

Iterable<String>

, e.g.

List<String>

. 3 - Use

Array::asIterable

.

Are there solutions (other than #1) that do with the method signature?

No, if the method signature declares an

Iterable

you cannot pass something that's not an

Iterable

. That's like passing a

String

where a

List

is expected. The types do not match up.

But isnt an array an iterable?

No, it is not.

I know it isnt in Kotlin, but java it is right? isnt that how old school

for

is possible during compile-time

No. The foreach-loop on arrays is special cased, it does not compile to an

iterator

method call.

Ah
