The Similarities of Swift & Scala

You've probably heard about Swift by now, even if nobody actually knows it yet. And if you have, you might have noticed that it has a few things in common with Scala. You wouldn't be the only one:

But if you're not yet persuaded, or if you'd just like to see these similarities fully explored, Jacob Leverich has you covered with "Swift is a lot like Scala."

Leverich's rundown of the similarities is thorough and well-organized, presenting a wide variety of common programming techniques compared in Swift and Scala with side-by-side code snippets. Something like this:

It's all split up into a handful of broad concepts:

  • Basics
  • Collections
  • Functions
  • Classes

So you can see how where they match up and where they differ. It's an interesting look at the two languages and the ways they overlap, and Leverich is careful to clarify that many of these similarities are fairly superficial. When you dig deep enough, he says, they start to disapper:

...Swift's runtime environment is quite distinct from Scala's, and is perhaps the most interesting aspect of the new language. Scala compiles to the JVM, uses garbage collection, and its object model transparently integrates with Java. Swift compiles to native code, uses automatic reference counting, and its object model transparently integrates with Objective-C. Thus, the similarity between the two languages does not extend much below the surface.
