Embedded Swift is a new compilation mode introduced by Apple, specifically designed for programming constrained embedded devices. It allows developers to use Swift, a language known for its ergonomics and safety features, in environments traditionally dominated by C and C++. Embedded Swift is a subset of Swift, covering most of the language features such as value and reference types, closures, optionals, error handling, and generics. However, it excludes certain features like runtime reflection to meet the constraints of embedded environments, which often require small and simple binaries due to limited memory and CPU performance.

Embedded Swift is currently an experimental feature and is best used with preview toolchains from swift.org. It supports ARM and RISC V chips and is not hardware-specific, making it adaptable to new instruction sets. Developers can use it to build various electronics projects, including smart home devices like a HomeKit color LED light, as demonstrated in the session. Additionally, Swift's interoperability with C allows developers to access APIs in vendor SDKs, enabling them to control hardware components like LEDs.

For more information, you can refer to the session Go small with Embedded Swift (00:46) which provides an introduction and demonstration of Embedded Swift.
