I hear iOS devs say that, but code editing in XCode for me is very uncomfortable compared to Webstorm, Visual Studio Code or Visual Studio. There are no tabs for open files to speak of (XCode opens a new XCode for their "tabs"), the UI is very cluttered and things are quite hard to find if you don't know where they are - and it doesn't help that the UI keeps shifting around in updates, making Googling stuff harder because a lot of images of things became deprecated.
Not sure where this is coming from but Xcode has been working pretty well for most of us.
