Swift Format in Xcode 16
In Xcode 16, Apple quietly introduced the ability to format your Swift files using Swift Format. I’m a long-time user of SwiftLint, but having such a tool built into Xcode would be a great convenience, so I decided to give it a try. Here is my description of why I use such a tool, how well it works compared to the alternatives, and how I configured it for my own purposes.

The name Apple chose is logical but confusing. I had experimented with Nick Lockwood’s SwiftFormat a few years ago, but found that I preferred SwiftLint, so I stuck with the latter. When I saw that Xcode included Swift Format, I assumed that they had acquired Nick’s formatter but it appears to be a different tool, officially called swift-format. It’s downloaded as part of the toolchain when you install Xcode 16, so no further installation is required.

This fixed the indentation and the whitespace issues. Interestingly, it split the long function call and definition over multiple lines, but still with more than one argument per line.

A downside of using swiftlint -fix , and presumably any other formatted that runs during a build phase, is that it breaks the undo stack.
