SwiftCLI
A powerful Swift framework for building command-line interfaces, from simple scripts to complex multi-command tools.
What is SwiftCLI?
SwiftCLI is a framework for building command-line interfaces in Swift. It simplifies creating CLIs by handling argument parsing, command routing, option validation, and help generation, allowing developers to focus on their tool's logic rather than boilerplate code. It supports everything from single-command tools to complex multi-command applications with nested command groups.
Swift developers who need to build command-line tools, whether for internal scripting, distribution via Homebrew, or public open-source projects. It's especially useful for those creating tools with multiple commands, options, and requiring shell completions.
Developers choose SwiftCLI for its type-safe, Swift-native API that reduces boilerplate, its comprehensive feature set (including Zsh completions and external task execution), and its flexibility—offering sensible defaults while allowing deep customization of parsing, routing, and help message generation.
