Can somebody explain "KoinIOSKt.doInitKoinIos()" to me? I'm trying to understand the implicit logic that resolves doInitKoinIos to the function initKoinIos. Where is KoinIOSKt defined?

[russhwolf]

Swift/Obj-C treat functions whose name starts with init as initializers, so the Kotlin compiler automatically adds a do on the front of the function name. Arguably we should rename that function so it’s less confusing. KoinIosKt is a prefix/namespace that is implicitly added to top-level functions in the file KoinIos.kt. This is similar to the syntax you get with Java interop for top-level functions.

Thanks for the explanation. I had searched for both "KoinIosKt" and "doInitKoinIos" in the project and didn't find anything. When searching on Google, I was surprised to see that even Google didn't have any results. I don't remember the last time I saw that. :-)

Thank you for the explanation, Russell. I also searched for this on Google and didn’t find anything. It would be helpful to include this detail in the official documentation (Interoperability with Swift/Objective-C).

BTW, I noticed that Obj-C attaches special meaning to functions whose name begins with alloc, new, copy, mutableCopy as well as init (Advanced Memory Management Programming Guide). It appears that the Kotlin compiler automatically adds the prefix do to such function names. Can somebody knowledgeable confirm this?
