![]() Īlthough it was originally marketed as simply "version 10" of Mac OS (indicated by the Roman numeral "X"), it has a completely different codebase from Mac OS 9, as well as substantial changes to its user interface. However, the current macOS is a UNIX operating system built on technology that had been developed at NeXT from the 1980s until Apple purchased the company in early 1997. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Mac computers since their introduction in 1984. ![]() if let bestPlayer = players.The history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2011 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. Use optionals when you might have an instance to return from a function, or you might not. ![]() You can even write concurrent code with simple, built-in keywords that define asynchronous behavior, making your code more readable and less error prone. Memory is managed automatically using tight, deterministic reference counting, keeping memory usage to a minimum without the overhead of garbage collection. To best support international languages and emoji, strings are Unicode-correct and use a UTF-8-based encoding to optimize performance for a wide variety of use cases. ![]() Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. Even better, you don’t even need to type semi-colons. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. ![]()
