Nerval's Lobster writes: When Apple rolled out Swift last summer, it expected its new programming language to eventually replace Objective-C, which developers have used for years to build iOS and Mac OS X apps. Thanks to Apple's huge developer ecosystem (and equally massive footprint in the world of consumer devices), Swift quickly became one of the most buzzed-about programming languages, as cited by sites such as Stack Overflow. And now, according to new data from TIOBE Software, which keeps a regularly updated index of popular programming languages, Swift might be seriously cannibalizing Objective-C. On TIOBE's latest index, Objective-C is ranked fourteenth among programming languages, a considerable drop from its third-place spot in October 2014. Swift managed to climb from nineteenth to fifteenth during the same period. "Soon after Apple announced to switch from Objective-C to Swift, Objective-C went into free fall," read TIOBE's text accompanying the data. "This month Objective-C dropped out of the TIOBE index top 10." How soon until Swift eclipses Objective-C entirely?
