## What it is
The Swift programming language: a high-performance, memory-safe systems and application programming language with a modern syntax and seamless C/Objective-C interoperability. This repository contains the Swift compiler, standard library, and toolchain sources.

## Use cases
- build ios and macos apps in swift
- write a memory-safe systems programming language project
- contribute to the swift compiler
- build a custom swift toolchain from source
- learn a modern statically typed language
- interoperate with existing c and objective-c code

## When to choose
- you are developing for apple platforms or want a safe, fast compiled language
- you need C/Objective-C interoperability with modern language ergonomics
- you want to contribute to or study a production-grade compiler

## When to avoid
- you need a language for embedded microcontrollers with tiny footprints
- your team is standardized on another ecosystem like JVM or .NET
- you only need a scripting language without a compile step

## Facets
- artifact type: cli-tool
- maturity: stable
- function: compiler, programming-language, interpreter, developer-tools
- domain: programming-languages, compilers, developer-tools, cross-platform
- platform: windows, cpp, cross-platform
- tags: swift-language, compiler-toolchain, memory-safe, objective-c-interop, apple-ecosystem, macos, linux, swift
