AppCode integrates with the Prettier code formatter. You can reformat selected code fragments as well as entire files or directories using the Reformat with Prettier action. AppCode adds this action as soon as you install Prettier as a dependency in your project or globally on your machine, Prettier is available in
Moreover, the key code style rules from the Prettier's configuration are applied to the AppCode Code Style settings. As a result, generated code (e.g. after refactoring or quick-fix) and the code that is already processed with Prettier are formatted consistently.
