Compiler Error This week's Compiler Error has a theme: Swift on Other Platforms 1 - DroidUI builds on earlier efforts to get Swift compiling for Android by adding interconnects to existing Java-based libraries so an entire app could be built. 2 - project1 is an attempt at implementing an x86 kernel completely in Swift that can run bare metal on Intel Macs and PCs. 3 - swift-embedded is a toolchain to compile Swift so it can run on a microcontroller directly with no host operating system. 4 - SwiftWasm is a toolchain allowing swift code to be compiled to WebAssembly, with full bridging to the DOM.
