Hi Again Everyone! 👋

Trying to setup Ktor and Coroutines in a KMM library project. I can’t sync, I keep getting errors that none of the dependencies can be resolved for the ios targets. Errors in the screenshot. My build.gradle.kts is posted in the 🧵 . Any Ideas? Google has been no help at all.

This is probably because those library versions don't have the ARM64 targets yet. E.g. kotlinx.coroutines added support for the ARM64 targets in v1.5.2.
