Xcode 10
Apple has a winner with Xcode 10. With macOS Majave it gained Dark Mode which many of you have seen in other IDE’s and pro level tools. Not only does it make it look futuristic and cool, it is actually reduces eye strain by reducing how much brightness is pushed at you.
Beyond that, I’m having trouble putting my finger on what is so much better about Xcode 10. It feels like I am fighting it less often. Maybe it is because I have gotten more experience with it over the years, but I think something is different. It’s like the searches are more accurate and navigation takes you where you expect it too. Autocomplete seems to work better too. It is certainly more stable than Xcode 9, even while still in beta.
I’m not quite sure I would say that Apple has caught up to Jet Brains or Microsoft for IDE’s, but I think they are closing the gap.
