i've been able to compile library for iphone target and now i have a stupid question - can i use it inside obj-c or swift project? and how to link it properly?

Hello.
How does your library interface look like? Do you want to call Kotlin from Objective-C/Swift?
If so, does your library interface use anything except primitive types and pointers (CPointer<...>)?

[abatutin]

so far i have a simple

fun test() {
    println("Hello, World!")
}

[abatutin]

code in my lib

and i want to call it form objc/swift

Embedding Kotlin Native code as a library is not quite ready yet.
You can try to add main function to Kotlin Native part, and call your true main from it. In this case Objective-C/Swift part should be compiled into static library and supplied to Kotlin compiler through -linkerOpts.
Then, to call Kotlin function from Objective-C you can either
1) Export the function from Kotlin with internal annotation @konan.internal.ExportForCppRuntime(<name>) and import it in Objective-C by declaring it as usual C function,
or
2) Pass Kotlin functions to Objective-C as pointers using staticCFunction.

The second approach will become simpler due to Objective-C interop.

i see, thnx

[abatutin]

staticCFunction worked, thnx

[abatutin]

do you know if embedding kotlin as lib to c/objc/swift is going to be a thing?

[svyatoslav.scherbina]

It will be supported, but there is no ETA.
