Tuist

Tuist provides a command‑line workflow for generating and managing Xcode projects, aiming to keep large, modular iOS codebases maintainable. It abstracts the structure of Xcode project files into a declarative description, allowing developers to create, update, and share project configurations without manually editing the IDE’s project files. The tool also offers a registry for pulling only required source components, which can reduce local and CI build sizes.

Built‑in features address common productivity bottlenecks: a cache reuses compiled binaries to shorten build times, selective testing runs only tests affected by recent changes, and automated detection highlights flaky tests that fail without code modifications. Build and test insights are collected across local and CI environments, helping teams spot slowdowns and failures early. Additionally, Tuist can generate shareable app previews via URLs, bypassing TestFlight for quick visual feedback.

The platform is open source, with a community of thousands of contributors and teams using it in production. It integrates with existing Xcode workflows, providing documentation, API references, and a public dashboard for monitoring performance and adoption.
