SwiftUIPreviewRunner is a tool that allows users to paste SwiftUI code and see live previews without needing Xcode, providing a faster and lighter alternative for quick UI experiments. It compiles and runs SwiftUI code asynchronously, improving performance and user experience. The tool supports integration with Codex and Tauri, allowing for enhanced web-based UI control over native SwiftUI previews. Users should exercise caution as the previews run in the host app process, making it unsafe to execute untrusted Swift code.
Paste SwiftUI code, see it live. No Xcode. Contribute to AryanRogye/SwiftUIPreviewRunner development by creating an account on GitHub.
