Hey!
I'm trying to access types and methods of the stdlib (specifically: Sequence) from Swift.
It seems, that the generated framework headers only include definitions for my code but misses a lot from the stdlib. So there actually is the compiled KotlinSequence accessible but all the factory and extension functions are not -- which renders it pretty useless.
Is there a way, to make some or all types and methods available in a compiled native xcode framework? Any hints are much appreciated!

The only option available currently for extensions and factories is to add simple wrappers for these functions to your module, e.g.

fun <T : Any> generateSequence(nextFunction: () -> T?): Sequence<T> = kotlin.sequences.generateSequence(nextFunction)

Oh ok. Actually that’s what I started with. But that felt like too much boilerplate to write

[Brian]

Wouldn’t it be possible, somehow, to add definitions to the headers? Maybe via a Gradle config?

… or maybe let me ask my last question differently 😉 : is this something that will be improved in the future?

[svyatoslav.scherbina]

We have no specific plans for improving experience in this particular case with Sequence.
