That's kind of one of Swift's things - it is designed to be as accessible as a scripting language but scalable to full applications and system software. Ideally it gives you some of the convenience and accessibility of a language like Python, combined with runtime efficiency of a language like Objective-C. print("hello, world") is a cute example since it's a valid program in both Python and Swift. (Though I still haven't forgiven Python for removing the print statement, which dates back to BASIC antiquity.)
