Kotlin Native using 1.0.0-beta-1:
I tried to create a customized version of the iOS HttpClientEngine. I copied the source code from the original IosClientEngine, added necessary annotations to make it compile but it rises compiler errors:

Errors mentioned:

I suspect it's because of the DefaultHttpRequest but I have no clue how to work around this. Any idea?

The iOS engine is a link-time dependency and the engine symbol name have to be the same for now.

You could resolve it by removing adding ktor-client-core-ios and create the method:

fun IosClient(): HttpClientEngineFactory<IosClientEngineConfig> = 
  TODO("your implementation")

[e5l]

Could you list your project configuration to clarify the issue?

issue persists after removing the ktor-client-core-ios dependency
