Hi all, I am having some problems using KTor and coroutines in the iOS side. I am using 1.3.9-native-mt-2 but I can't create Ktor-HttpClient in the iOS side. I don't know if I am missing something. My dependencies are:

kotlinVersion = "1.4.0"
ktorVersion = "1.4.0"
coroutineVersion = "1.3.9-native-mt-2"
serializerVersion = "1.0.0-RC"

internal actual val ApplicationDispatcher: CoroutineContext  =
    NsQueueDispatcher(dispatch_get_main_queue())

internal class NsQueueDispatcher(
    private val dispatchQueue: dispatch_queue_t
) : CoroutineDispatcher() {
    override fun dispatch(context: CoroutineContext, block: Runnable) {
        dispatch_async(dispatchQueue) {
            block.run()
        }
    }
}

But when I try to create HttpClient this exception is thrown(kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen kotlinx.coroutines.ChildHandleNode):

private val client by lazy {
     HttpClient() {
         install(JsonFeature) {
             serializer = KotlinxSerializer(nonStrictJson)
         }
         install(Logging) {
             logger = Logger.DEFAULT
             level = <http://LogLevel.INFO|LogLevel.INFO>
         }
     }
}

Has anyone had the same problem? Thanks in advance.

Use Dispatchers.Main and Dispatchers.Default rather than custom dispatchers, now that they are available and work

Also most issues with Ktor native (the one you encountered included) are fixed in 1.4.1. The last blocking one for me is https://youtrack.jetbrains.com/issue/KTOR-1073

Thanks @ribesg I've tried this but it doesn't work. I've updated my dependencies to:

kotlinVersion = "1.4.10"
ktorVersion = "1.4.1"
coroutineVersion = "1.3.9-native-mt-2"
serializerVersion = "1.0.0-RC2"

But now in iOS side when HttpClient calls get() method this exception is thrown:

kotlin.IllegalStateException: There is no event loop. Use runBlocking { ... } to start one.
