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!

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

The

ios {}

builder creates an

ios

source in addition to

iosX64

and

iosArm64

, but the IDE interprets it as common

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

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

sorry, I was stating what targets it creates

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