# Re-running a failed build

When a build fails for a reason that has nothing to do with your code — a flaky
test, a timeout, a signing hiccup — you can queue it again without leaving the
run.

## Rebuild the run

Open the run from the **Runs** tab, or from Recent Builds on a workflow. The
**Rebuild** button is in the toolbar.

Confirm, and Xcode Cloud queues a new build using the same workflow and git
reference.

## When Rebuild is dimmed

A run that hasn't finished can't be re-run. Wait for it to complete, then try
again.

## If the rebuild is refused

Xcode Cloud turns down some runs — usually because the reference no longer
exists or the run is too old. Start a fresh build from the workflow instead.

## Faster ways in

- Ask Siri: "Re-run my last build in Mobile Builds."
- The Recent Build Runs shortcut result has a **Re-run** button on each finished
  build.
