xbq - Xcode Build Queue

xbq is a command-line interface (CLI) tool designed to manage serial Xcode builds for projects utilizing Git worktrees. It aims to solve the problem of duplicating large `DerivedData` and Swift Package Manager (SPM) resolution caches when running multiple concurrent AI coding sessions (e.g., Claude Code) on the same Xcode project. By routing all build and test requests through a single 'main' repository, it significantly reduces disk space usage and prevents `DerivedData` corruption. The current stable version is `0.6.0`, with a consistent, albeit irregular, release cadence that introduces new features and fixes. Key differentiators include its snapshot-based build process (no commit required), strict serial queue enforcement, and robust worktree management, making it an essential tool for environments leveraging AI-driven development with Xcode.
