It has bugs, and most frustrating are the regressions (for example, in some past Xcode they broke option-drag-to-copy-text editing but eventually fixed it; now in Xcode 9, it’s broken again — or at least so unreliable that I never bother to try copying that way anymore and it’s useless). While I’m partial to terminal-based editors anyway, I never felt like I required them until Xcode 8.x or so.

I really don’t understand Apple’s development tools strategy. In the old days, the “separation of concerns” that was Project Builder and Interface Builder with other developer apps and command-line tools, etc. made a lot of sense. Ever since they created the UI abomination that is Xcode 4.x and tried to shove every single thing into the same program, it’s been unstable and aggravating to use. And don’t let the 9.x version fool you; these are iTunes-style marketing versions, Xcode “9” represents AT BEST an Xcode 5.1.0.2beta3 level of usefulness.
