Hello, Before kotlin 1.6.0 I was able to map my sealed classes to swift enums:

enum ResponseStateEnum<T: AnyObject> {
    case loading
    case success(T)
    case error(RestClientException)
    
    init(_ state: ResponseState<T>?) {
        if state is ResponseStateLoading {
            self = .loading
        } else if let state = state as? ResponseStateSuccess<T>, let content = state.content {
            self = .success(content)
        } else if let state = state as? ResponseStateError {
            self = .error(state.exception)
        } else {
            fatalError("ResponseStateEnum not syncronized with ResponseState class")
        }
    }
}

now I get this log

(lldb) po type(of: state!)
PKMMResponseStateLoading

(lldb) po state is PKMMResponseStateLoading
false

Did anything change about sealed classes?

I was having this issue on non-debug builds. I've investigated and it looks like it was about xcode's optimization level build settings. I wonder why this happens
