Also, join us for #CompleteTheCode and Compiler Error, two segments that test both your knowledge and our knowledge on Swift, Apple, and all things development!

Your hosts for this week:

• Spencer Curtis

Be sure to tweet us with hashtag #CompleteTheCode if you know the answer!

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.
