Hey guys. Starting to work with apollo3 and KMM. I'm wondering why this is an assertion during execution
```assertMainThreadOnNative()```
if I'm trying to execute a query. Why am I forced to do it on the main thread?

Hi :wave: That's a long story with some details <https://github.com/apollographql/apollo-android/blob/dev-3.x/design-docs/Threading.md|here>. The tldr; is that when we started, multithreaded coroutines were super experimental and we wanted to make everything work with the regular coroutines artifact

Everything is still executed on a background thread so it hasn't been a big limitation so far.

Also, something else is that there is no blocking call with `NSUrlSession` so you get a callback in a dispatch queue from where you need to resume a coroutine.

If that coroutine is the main thread then it's easy to get `dispatch_main_queue()` . If it's not, then it's not the same story

wow thanks <@U79JY5TL3> for the quick response. I'll take a look

Sure thing. Let us know if you have a different use case, we can look into it.
