Creating Matter devices with Apple’s showcase using Swift language on ESP32.

During WWDC24, Apple showcased the development of Matter devices using Embedded Swift on the ESP32 chip, enabling easy integration with HomeKit.
Embedded Swift is a subset of the full Swift language, designed to minimize binary size by excluding features like reflection. However, code written in Embedded Swift can still fully execute in Swift. Apple has been advocating for this format for some time now, and has been increasing examples since April. However, it remains an experimental project.
Matter is a universal standard for connecting IoT devices, which is poised to become the standard for home device connectivity in the future.
The example project that Apple demonstrated utilizes the ESP32-C6 module with a RISC-V architecture, using the ESP-IDF and ESP-Matter development kits. While these kits typically use the C language, in this case Apple created Swift bindings to sufficiently support the creation of smart lightbulbs.
