should i still be using this for usage Flow in swift code? https://github.com/JetBrains/kotlinconf-app/blob/master/common/src/mobileMain/kotlin/org/jetbrains/kotlinconf/FlowUtils.kt

Broadly, the pattern of wrapping suspend and flow APIs in functions that take lambdas so they can be called from Swift is a good one. Whether you want to use that exact implementation vs a more complex one (for example to add error handling, or structured concurrency support) is up to you and your project's needs.

I do heavily since all my view model code is in Kotlin and exposed through flows. See also my answer to Gurupad’s post right above yours
