I only use Swift for a side project, but I found myself splitting my time between AppCode and XCode. AppCode is nicer in terms of feature set (both in completeness and in my familiarity with the shortcuts), but I find XCode is <i>much</i> faster. If I'm working on something with a bunch of renaming/refactoring/etc, I'll do it in AppCode; if I'm more or less just typing and running tests, I'll do it in XCode.<p>So, while this announcement is sad, I can't say it's shocking. In other languages I know, IntelliJ products are significantly better than the competitors. For Swift, it's a bit more... meh.
