SwiftLint was developed by the nice folks @realm. It’s a great open-source tool for establishing and enforcing a formal coding style in Swift. It runs on the command-line, but it can be hooked into Xcode directly too. It also boasts an “autocorrect” feature, which sweeps through your code and automatically fixes the most trivial violations (e.g., colon positioning, double white spaces, etc.). I created a Git commit hook which does exactly this, every time a team member makes changes.
