Kotlin Multiplatform: Memory management old and new way

on YouTube ↗58m

" summary

Explains concrete failures and fixes when sharing objects across threads in Kotlin Multiplatform: coroutines throw invalid-mutability or context-bound exceptions when switching between Dispatchers.default and main unless objects are made thread-safe; examples use freeze/unfreeze and Worker.start with futures and callbacks to show the invalid mutability exception and the atomic reference workaround; shows detached graph and background Worker use and how to return results to main; describes migration to new memory model (K/N 1.6) where freezing is removed and default dispatchers bind to iOS global queue, but notes library support, Xcode 12.5, and special coroutine branches are required.
