hey folks, first time trying Kotlin Native. Is Xcode mandatory for Kotlin Native ? I am trying to build the demo project https://github.com/kotlin-hands-on/intro-kotlin-native but I am getting

23:30:05: Executing tasks ':assemble :macosMainBinaries :macosTestBinaries --stacktrace'...


> Configure project :
Kotlin Multiplatform Projects are an experimental feature.

* What went wrong:
Execution failed for task ':cinteropLibcurlMacos'.

I am confused as i can’t see anywhere in the docs Xcode as prerequisite.

Xcode must be installed to build macOS/iOS targets

sure, to build to a specifc target/platform, in your case macos (by your build command :macosMainBinaries :macosTestBinaries ) you have to have the platform specifc build tools
