It’s much much better than Xcode for autocomplete, code highlighting and refactoring. It’s just a better swift editor than Xcode basically.

Disclaimer: I’m a long time IntelliJ user so I find the environment more comfortable in general, not sure if that’s the case for long time Xcode users.

Just started using it out of frustration with XCode stability, works really well. I too have been using a few of the Jetbrains products through the years.
