Is there an example of a full Kotlin MPP Mobile project? I mean Gradle Kotlin DSL, Android & iOS app with 100% Kotlin

That's exactly what I'm stuck on. It looks like you can but I have no idea how: https://github.com/JetBrains/kotlinconf-app/blob/master/common/src/iosMain/kotlin/org/jetbrains/kotlinconf/storage/PlatformSettings.kt

That’s what I understood but I find the lack of resources and example very weird

Yeah exactly. All examples stop at calling Kotlin from Swift, which looks to be "relatively" easy. But examples of calling Swift from Kotlin are no where to be found

I’m reading things about Kotlin Native not supporting Swift, so libraries which are not working when called from an ObjC project would not work in Kotlin Native

Yeah that makes sense I suppose, that's why you need the @objc annotation on any swift classes you want to access

I found this https://kotlinlang.org/docs/reference/native/gradle_plugin.html

This document describes Kotlin/Native experimental Gradle plugin, which is not the plugin yet supported by IDE or in multiplatform projects

Yeah but C interop must be supported as it's found in the sample projects

Yes

Just ran the demo project I have and it looks like the first build causes the multiplatform gradle plugin to download and link the iOS platform imports. Try building and you should be able to import

platform.*

classes, which are iOS platform Objc classes

The repo I linked doesn’t use the MPP plugin, right?

No, that's link is for creating Kotlin libraries to be used by Native/C code only

Well I’m not sure, this looks like a Kotlin iOS app using share Kotlin code https://github.com/JetBrains/kotlinconf-spinner/tree/master/clients/ios
