"For anyone who has been programming in a modern language such as Ruby [1995], Python [1991], Clojure [2007], Haskell [1990], etc, and who was put off developing iOS apps by Objective-C, Swift marks a new era."

You say modern but I don't think it's really what you mean here.

Your descriptions of Ruby vs Obj-C make it seem that really what you mean is high-level; that is, to a newer programmer, easier.

These languages (Haskell excepted) make it very easy to do simple things. Describing them as "modern" in contrast with the implicitly antiquated Obj-C makes it a little hard to take your assertions seriously.

Verbosity is a claim to make, age is not.
