About:
Nef is a command-line tool designed to enhance Xcode Playgrounds by providing steroids-like capabilities. It enables developers to compile and integrate Playgrounds within standard Xcode projects, bridging the gap between rapid prototyping and robust application development. The tool focuses on improving workflow efficiency and code reusability for Swift developers.
Key Features:
  • Compile Xcode Playgrounds into framework-compatible modules
  • Integrate Playgrounds directly into Xcode projects
  • Generate documentation from Playground pages
  • Support for Carbon and Jekyll integration
Use Cases:
  • Building reusable libraries using Playgrounds for rapid prototyping
  • Creating documentation sites from Playground content
  • Embedding Playgrounds within iOS/macOS applications for testing
Alternatives:
  • Swift Playground – Apple's native app is for learning, while Nef focuses on production workflows and project integration.
  • CocoaPods – Nef is not a dependency manager but a tool to leverage Playgrounds for development and documentation.
