Danger Swift is a tool that automates the repetitive parts of code review. If you've ever found yourself leaving the same comment over and over on pull requests, "you forgot to update the changelog," "this file needs tests," "fix your formatting", this tool handles those automatically. It runs as part of your continuous integration pipeline and posts comments directly on pull requests, so reviewers can focus on the actual logic rather than policing house rules. You write a "Dangerfile" in Swift that inspects metadata about each pull request: which files changed, what lines were added or removed, who opened it, and so on. Based on that information, your Dangerfile can post messages, warnings, or even block the PR from merging if something critical is missing. For example, the README shows a rule that checks whether someone modified source files without updating the CHANGELOG, if so, it leaves a warning comment automatically. Teams using Swift who want to enforce project conventions without nagging people would get the most out of this. A startup with a small engineering team might use it to make sure every PR includes a test file, or that nobody accidentally commits debug code. Open-source maintainers could use it to verify that contributors have signed a CLA or followed branding guidelines. The plugin system lets you share rules across multiple repositories, so an organization can codify its standards once and reuse them everywhere. The project is specifically the Swift flavor of a broader tool called Danger (the original is written in JavaScript). It's worth noting that you can run it on macOS or Linux, and it integrates with GitHub Actions. The README points to the main Danger website for full documentation rather than covering everything itself.
