In October Apple filed for the trademark "Swift" in the U.S., Europe and China. This week, Apple has filed for the alternative trademark "Apple Swift" in the U.S, Europe and China. Swift or "Apple Swift" is a multi-paradigm, compiled programming language created by Apple for iOS and OS X development. It was first introduced during Apple's 2014 Worldwide Developers Conference. Apple states that "Swift is an innovative new programming language for Cocoa and Cocoa Touch. Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast." UPDATE Dec. 01, 2014. Apple adds filing for Swift logo/icon.
