One thing I‘ve really come to appreciate (applies to all code editors) is to actively use keyboard shortcuts for moving selected lines up/down, and for deleting the current line. Vim users will be used to this anyway, but for the rest of us it’s a great way to code faster. The other thing (since Xcode‘s clipboard feature is IMO clunky) is to use a clipboard manager with the history set to a decent size. I use Paste (happens to come with SetApp) and never once lost a copied snippet - it‘s rock solid. I’ve developed a habit of just copying whole files in case I want to revert to that state (or partially) later.
