If you meant are pretty far I disagree with you. 'Flavor of the year' is a figure of speech meaning they are a fad, and indication is that GP is very correct about a lot of these. Ruby is already yesterday's news, with the MEAN stack and even newer ideas taking its place. Swyft is very new and replaces Objective-C with a C#/Java-like language, which begs the question why don't we just use those?
Yeah, that was a typo, I meant "are pretty far".
I don't know how Ruby can be included in the list of "fad" languages:
fad = an intense and widely shared enthusiasm for something, especially one that is short-lived and without basis in the object's qualities
It's been around for 20 years now, and was quite heavily used for a number of those years. Yeah, it's on the decline, and there are better alternatives available for its most common use, but that still doesn't qualify it as a "fad", any more than Cobol, C, or even Perl, are fads.
Swift is on the other side of the spectrum -- new, but it has a backing of a company with power to force an army of developers to use it, and hence its adoption is quick and likely to be long lasting. Again, we're not talking about some random "cool" language of the year that will die out before seeing any real use.
These are simply not languages that I think of when I think of "flavour of the year". I think your bar for that description is much lower than mine.
