I have a working KMM module using Ktor client on iOS and Android. Trying to add macOS support. I use the following pattern:

GlobalScope.launch {
    launch(ApplicationDispatcher) {
       client.get {
       }
    }
}

but when testing with a macOS SwiftUI app, I get the following:

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

but runBlocking cannot be used in the common code. Any solutions to this? Is the above ‘canonical’ way to make Ktor client calls in common code?

Define your own with expect/actual

Or copy mine https://github.com/mpetuska/template-kmp-library/blob/master/test/src/commonMain/kotlin/runBlockingTest.kt

runBlocking exists in all targets except JS.

I have a lib that you can use it in common code if you are not using JS. For testing I have another artifact based on what I could see in the turbine repository by cashapp/square

I incorporated an expect/actual of a runBlocking wrapper, ran it and the same result. I suspect it is related to some other setup needed for Ktor on macOS. Will keep trying things. Thank you both for the links.

You can use Dispatchers.Main with the native-mt version of kotlinx.coroutines

MainScope() would work as well.

I changed to using ktor-client-ios for macOS, and also turned on this switch. All working now.
