Compare Builds

Quick Start

You'll typically receive two build identifiers (IDs, dashboard URLs, or branch names). Follow these steps:

1. Run tuist build list --json to find builds on each branch.
2. Run tuist build show <build-id> --json for both base and head builds.
3. Fetch sub-resource details: targets (tuist build xcode target list <id> --json), issues (tuist build xcode issue list <id> --json), and cache tasks (tuist build xcode cache-task list <id> --json).
4. Compare duration, status, cache hit rates, and other metrics.
5. Summarize regressions, improvements, and recommendations.

If only one identifier is provided, use the project's default branch as the baseline.
