As was said during the Q3 rankings which marked its debut, “Swift
is a language that is going to be a lot more popular, and very
soon.” Even so, the growth that Swift experienced is essentially
unprecedented in the history of these rankings. When we see
dramatic growth from a language it typically has jumped somewhere
between 5 and 10 spots, and the closer the language gets to the
Top 20 or within it, the more difficult growth is to come by. And
yet Swift has gone from our 68th ranked language during Q3 to
number 22 this quarter, a jump of 46 spots. […] Given this
dramatic ascension, it seems reasonable to expect that the Q3
rankings this year will see Swift as a Top 20 language.
Not sure if Swift could be gaining in popularity more quickly than this.
