Kotlin Multiplatform iOS build times: what's actually driving the cost
A recent article, The Hidden Cost Behind Kotlin Multiplatform on iOS, looked at what KMP does to the iOS edit/build/run feedback loop. It’s a good question to ask and the article also comes with a ben...

Spicy #AndroidDev take:
To do KMP on Android you need to be good at Kotlin, understand iOS internals, and how KMP does things on iOS.
In a traditionally 50% iOS engs 50% Android team, the talent pool for this is very very small.

Always great to hear feedback from iOS folks using KMP and Compose Multiplatform!
So yes after getting my hands dirty with Kotlin multiplatform the obvious next step would be to try Compose multiplatform. Which I did. And yes it’s a game changer.

yup it's fully KMP/jpcompose and works great on Android and iOS!! But we're always interested in connecting with more KMP people to get help and tips.

I've been losing my mind for the last few evenings trying to figure out how to write a KMP compatible Gzip decompression method
JVM & Android were easy but iOS was driving me crazy with zlib C interop and alloc calls!
TIL it turns out Okio can do it all, in two lines of code 😂

They dont want to learn a new language, lose their tooling, deal with multiplatform complexity.
