Hi, We have a naming conflict on Swift code which use our Kmp library. Is there a way to prefix all class names which generated by Kmp for iOS/Swift?

I think you should be able to use ObjCName for that - https://kotlinlang.org/docs/native-objc-interop.html#name-translation

ObjCName can help to transform individual classes, I would do it for every classes in my library

[Jeff Lockhart]

Kotlin types are prefixed in Objective-C with a prefix derived from the framework name. But in Swift, the prefix is removed, e.g. (for a framework Foo):

__attribute__((swift_name("Bar")))
@interface FOOBar

Because Swift has module namespacing, ObjC's convention for type prefixing is optional in Swift.

If you run into a situation where two modules used in the same file have conflicting types, you can use a local typealias to disambiguate, e.g.:

typealias AMyClass = ModuleA.MyClass
typealias BMyClass = ModuleB.MyClass

That would be an option, but we would like to have the same prefix for every classes from the Kmp library in Swift. It’s easier to keep track

[Jeff Lockhart]

I don't believe there's an option to globally prefix all Kotlin types in Swift.

We need to use either ObjCName annotation and/or Swift’s typealias then. Thanks @Jeff Lockhart, your tips is really helpful
