During the keynote, Federighi showed several slides demonstrating Apple's claimed performance boosts for common programming tasks over their equivalents in both Python and Objective-C.Īccording to Apple's developer notes, Swift can replace entire lines of code with a single character, while named parameters brought forward from Objective-C are "expressed in a clean syntax" that makes APIs in Swift easier to read and maintain. Swift works on its own or side by side with the object-oriented language Objective-C, which dates back to the 1980s and first debuted on NeXT hardware.
