## What it is
A collection of official example projects demonstrating Embedded Swift, a compilation mode of Swift for baremetal and embedded development on microcontrollers. Examples cover boards like ESP32, nRF52840, STM32, and Raspberry Pi with SDKs such as ESP-IDF, Zephyr, and Pico SDK.

## Use cases
- learn how to write Swift for microcontrollers
- blink an LED on ESP32 with Swift
- build firmware for Raspberry Pi Pico in Swift
- run Swift on baremetal ARM or RISC-V hardware
- explore Embedded Swift with Zephyr or NuttX RTOS
- control LED strips and UART from Swift on embedded boards

## When to choose
- you want to learn Embedded Swift through working, documented examples
- you develop in Swift and want to target microcontrollers like ESP32, nRF, or Raspberry Pi
- you need reference projects for ESP-IDF, Zephyr, Pico SDK, or NuttX integration

## When to avoid
- you need a production-ready firmware framework rather than examples
- your target hardware or RTOS is not covered by the included examples
- you are not using the Swift toolchain

## Facets
- artifact type: learning-resource
- maturity: active
- function: embedded, developer-tools, sdk
- domain: embedded-systems, hardware, tutorials, programming-languages
- platform: embedded, iot, cross-platform
- tags: embedded-swift, microcontrollers, esp32, stm32, nrf, raspberry-pi, example-projects, baremetal, firmware, zephyr, esp-idf, nuttx
