👋 I have an issue and was hoping to get some help, if it's a configuration issue or not.

With SKIE enabled, it seems the generated Swift interface is different than without, particularly with suspend functions + optional return type.

I have the following Kotlin code:

interface Foo {
	suspend fun getStringAsync(): String?
}

If I would like to implement the interface in Swift side, my code will have to be:

class FooImpl: Foo {
	func __getStringAsync() async throws -> String {}
}

Notice the return type is String, rather than String? as I would expect.

I have the following gradle configuration:

skie {
    features {
        coroutinesInterop = true
    }
}

----------

If however, I disable SKIE, it will look correct on the Swift side:

class FooImpl: Foo {
	func __getStringAsync() async throws -> String? {}
}

Am I missing something, or is this intended behavior?

Are you on the latest version 0.6.1? There was a bug fix for this in that version https://skie.touchlab.co/changelog/0.6.1
