How Swift Runs on Android — Swift SDK for Android and KMP

on YouTube ↗40m

" summary

Explains how Swift 6.3 enables running Swift on Android by providing an official Swift SDK for Android that cross‑compiles Swift into per‑architecture .so libraries (targeting Android API 28+), bundles prebuilt Swift runtimes, and already builds over ~25% of Swift Package Manager packages for Android. Describes interop via a Swift→Java wrapper generator called SwiftJav that produces JNI bindings, and how memory is handled across ARC and the JVM garbage collector using a SwiftArena; notes current limitations such as no SwiftUI, some missing Foundation APIs, and an approximately 80MB APK size increase.
