I have an interface Gateway and a class parameter KClass<Gateway> . But when I pass an instance of KClass<GatewayImpl> , the compiler complains. Is there a way around this? Casting works, so something is correct.

Use KClass<out Gateway>

Thanks! I thought I tried that, but turns out I forgot to remove the casting 😬
