In reading “The Swift Programming Language” to prep for my post on how Swift informs us about programming language trends, I was surprised at how straightforward the language’s features seemed:
I found myself nodding along with each feature introduced. Tuples: check. Named Parameters: check. Default Parameters: check. Protocols: check. Functions: check.
Although the forms of Swift’s various features differ from their analogs in other languages, conceptually, they are the same: the generic type system is similar to Java’s, and the tuples are close enough to Scala’s that all I need to do is understand the syntax.
It really is true that the more languages you know, the easier it is to “pick up” new ones. This is a great reason to learn a new programming language every year.
