Does anyone know if Kotlin suspend functions actually suspend on iOS and if so, how is it implemented on iOS?

About the same way as on the JVM. It's callbacks chains under the hood.

Thanks!

@louiscad sorry to bother you again but I couldn`t find more information about it in the documentation. Are they actually suspending or just blocking the thread?

They are suspending, which under the hood, is waiting for a callback.

You have access to

Continuation

in Kotlin/Native as well @Matteo Wohlrapp

suspendCancellableCoroutine

and other suspend primitives wouldn't be able to work just like on JVM and JS without that.
