Are there any conditional compile strategies? Something like If (android) {a=andA} else if (ios) {a=iosA}. I want to use interfaces to separate some platform-specific logic, then compile them according to different platform

[albertgao]

Well, I think I can just implement the interface in Kotlin with the iOS API then inject the generated framework at swift side. Same for android. No need for this kind of check.

You could also deploy expect/actual mechanism and compile different sources adhering to same contracts on different platforms

[albertgao]

@olonho Thanks! This is actually better. But I thought the multiplatform project hasn’t landed on KN yet?

[olonho]

Plugin support not there yet, keywords shall be supported

[albertgao]

@olonho Thanks for the hints! I just tried. IDEA said that multiplatform project is experimental and should be enabled explicitly. I tried to add expect "enable" in kotlin{ experimental{} } by the side of coroutines "enable", seems not the right way. Any ideas?

try -Xmulti-platform compiler switch

[albertgao]

gradle build -Xmulti-platform will yield Unknown command-line option '-X'.. Or is it a kotlinc parameter, but don’t know how to build with that yet. Will try later

Yes, it's a compiler switch and you may pass it via the gradle plugin using `extraOpts`:

konanArtifacts {
    program('foo') {
        extraOpts '-Xmulti-platform'
    }
}

But multiplatform support was added after the 0.5 KN release so you need to use either a compiler built from current master or set konan.version in your gradle.properties to some development version (e.g. konan.version=0.6-dev-822)
