Is it XCode or any other editor? Why do you use it over the other options?
Depends on the purpose of project.
If it is iOS app, it will be XCode as it has more features for that type of project.
If it is others, Sublime/VS Code/Atom. Any one of them. Its all mixed usage as I like to avoid the clutter and all these are customised to same type of Key Maps, theme, colour theme, code font etc. which is Sublime's.

I prefer xcode for native ios development since nothing seems easier than xcode for development in swift or objective c.
Since I generally work in hybrid app development using reactnative/tvjs , editing javascript files seems a little easier in vscode or atom with proper syntax highlighting and easy to use shortcuts.
A little while back I gave server side swift(perfect framework) a try and used atom editor.
