Embedded Swift is a subset of the Swift programming language designed specifically for constrained embedded devices. It includes most of the language features of full Swift, such as support for value and reference types, closures, optionals, error handling, and generics. However, it omits certain features that are not suitable for embedded environments, such as runtime reflection, to keep the binary size small and manageable.
Embedded Swift is used in various applications, including Apple's secure enclave processor, which benefits from Swift's memory safety. It is also suitable for programming microcontrollers in embedded devices, kernel-level code, and other low-level library code. The language is designed to be ergonomic, safe, and easy to use, bringing the benefits of Swift to the embedded development space.

What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
