"You choose the language that fits your goals best."

That's often an abused statement with no actual significance. If you are writing native iOS apps, you basically get two, maybe three, choices.

There is always a group of developers who will rush ahead and there's a group that will lag behind. It has more to do with human nature than the technical features of a language. That's why a year ago I started collecting a bunch of Swift resources in one place. Ive got almost 1500 urls.

Most blogs/articles on iOS development are now in Swift. If you are learning iOS 9, for example, it's easier to go with Swift. Swift is now the path of least resistance.
