# multiplatform

eposting from the general channel, as no answers there- maybe better luck here - this channel looks to be the most appropriate one? A multiplatform project, android and iOS. In common code in Kotlin, I have an interface - interface Idea. When in Swift, want to have a struct implement this interface, a.k.a protocol now in the Swiftland. Get a compiler error - inheritance from non-protocol type 'Idea'. In the generated objective-c file I see this - __attribute__((objc_subclassing_restricted)). Reading on it, all objective c protocols are restricted to classes. So how I do get around this problem - or no getting around and have to use classes in Swift😥?

Obj-C protocols are class-bound, so you can implement it only in class
“objc_subclassing_restricted” means your class isn’t public in kotlin common code

To directly answer, no structs

thanks. my interface is public is Kotlin common code, and I can see it in swift, just can apply to structs, only classes. But I get the point. Have to use Swift classes.

correction - can't apply to structs, only to classes
