Ask HN: Xcode users – how do you make it more usable?

I’ve come from JS in VSCode (with loads of extensions) to Swift in Xcode. In XCTest, I miss the red and green diffs between expected output and actual output. In Xcode itself, I miss the ability to perform code refactoring easily (extracting code to new files etc - more than just extracting to new functions). I also miss linting / prettier.

What tools and plugins for Xcode do you all use to make developing Swift in Xcode faster and easier? General Xcode hints and tips welcome.
