According to Tiobe, Swift's popularity is on the rise.
Ruby has slipped a notch to #18 & Swift has risen to #17.
To put this in perspective, ObjectiveC is currently #3 behind C & Java.
To further put this in perspective, Swift ranks just below R, Transact-SQL, PL/SQL, Pascal, & Delphi/Object Pascal.
Coming into the community at this point is somewhat surreal. There are a lot of grizzled ObjectiveC veterans who are grumbling about having to get on the learning curve again.
I see them as whiners - mostly because I am jealous of their experience and knowledge of the Cocoa and Foundation frameworks which I am struggling to come to terms with from a Swift-only perspective. To me, they already understand the hard parts of app development. Syntax-wrangling is just a way to keep things interesting.
But then I suppose that the mindsets are very different. Objective C is a product of the 1980's and it shows. Java was more of a 1990's mindset. Looking backwards through the lens of time that doesn't see like very much of a difference numerically but from a technical viewpoint they are very different indeed.
