Hello everyone,
I'm looking for solution to access files in desktopMain sourceSet from macosMain sourceSet.

Native (macOS) and JVM (desktop) targets are different platforms. You can't have one depending on the other.

You should read the documentation on available platforms and targets to better understand what is what.

https://kotlinlang.org/docs/multiplatform-discover-project.html
https://kotlinlang.org/docs/multiplatform-hierarchy.html

Yep, I understand both are different platform.
Suppose I wanted to check macOs bluetooth state is turned on or not.

How can I do it while supporting jvm(desktop) ?
Didn't found single resource for such use case

[ribesg]

You need to do it twice.

One solution might be to create a source-set which which is included in the desktop and macOs source-set and write expect/actual implementation for whatever you like(If need to wrtie platform specific implementations) or just write common code for both platforms.

@Devanshu Pathsariya If possible can you share some demo code or link for the same ?

[Devanshu Pathsariya]

To create the source-set

kotlin {
    sourceSets {

        val appleMain by getting
        val desktopMain by getting

        val desktopCommon by creating {
            appleMain.dependsOn(this)
            desktopMain.dependsOn(this)
        }
    }
}

Now you will have a new source-set and you can common code just like you would in commonMain source-set, only difference is code will be accessible only in appleMain and desktopMain and you need to write actual implementation in appleMain and desktopMain if you create a expect

With this change I'm not able to access any NS* classes for macos platform

[Devanshu Pathsariya]

You can't access the classes of different platform in the desktopCommon source set it is the common source-set for appleMain and desktopMain. You can define expect/actual in the desktopCommon.

Ok, trying to creating expect actual

[ribesg]

I don't think that's what you want.

I'm pretty sure you just want your app to run on MacOS/Linux/Windows, in addition to Android & iOS, but in your project you did it twice.

You need to choose between implementing your desktop app with Kotlin/JVM or with Kotlin/Native, or you'll just end up doing everything twice.

@ribesg I think to get the desired result have to add jvm and native target
