Does anyone knows why if I will set iOS target like this:

val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
        if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
            ::iosArm64
        else
            ::iosX64

    iOSTarget("ios") {
        binaries {
            framework(uniqueName)
        }
    }

Then everything works in iosMain, I can see whole syntax highlighting correctly.
Although if I set it like here:

ios {
        binaries {
            framework(uniqueName)
        }
    }

Everything related to iOS is red, I can’t see any import (although it compiles correctly) and syntax highlighting is broken.

Using ios {} sets up an intermediate source-set and the IDE currently has trouble detecting what platform APIs are available there. Expect that to improve over time as this family of issues is worked: https://youtrack.jetbrains.com/issue/KT-27801

I see, thanks for clearing up my doubts!

[Kris Wong]

to be more clear - the source set name needs to match a target name. so if you have iosMain, then you need a target named ios

[Kris Wong]

the second code block creates iosX64 and iosArm64

[russhwolf]

The ios {} builder creates an ios source in addition to iosX64 and iosArm64, but the IDE interprets it as common

[zalewski.se]

Interesting 🧐 Is it possible to see all the sources that has been generated?

[russhwolf]

sorry - it's configuration, not actual source code. It means the compiler will read things in the src/iosMain directory, for example, and apply them to both iosArm64 and iosX64 targets

[russhwolf]

which is why you were seeing that it compiles correctly

[russhwolf]

but the IDE still has trouble with it

[Kris Wong]

sorry, I was stating what targets it creates

[Kris Wong]

the problem is there's no target with the name ios

@zalewski.se you can navigate fully through the plugin source code and see what it is doing

Got it! Thanks guys for a detailed explanation, I’m gonna dive deep into plugin source code now to find out more 🙂
