On the native targets, the CIO engine doesn't support TLS, but the Darwin engine does. You can follow KTOR-7262 for updates on TLS support for the CIO engine.

I must use the Clash to bypass some blocking. Is there such a configuration in Darwin's engine that can bypass certificate checking?

now I use the Darwin engine on the macOS and finally the APP was running, thks ( p′︵‵。)

now i have a last question: How do I apply domain fronting to Darwin-powered HttpEngine to bypass SNI blocking in some regions?

This may be difficult: in Darwin engine, you cannot directly modify the SNI (iOS/Apple does not allow it).
But you can customize it through sslSocketFactory on the CIO or OkHttp engine.
