July 05, 2012, 4:56 PM — Thanks to the popularity of Apple's iPad and iPhone mobile devices, the Objective-C language has overtaken C++ in Tiobe's monthly assessment of programming language popularity.
Objective-C, the language used for developing applications to run on Apple's mobile devices, was ranked the third most-popular language in the July edition of the Tiobe Programming Community Index, followed by C++ in fourth place. Released this week, the index has Objective-C used by 9.335% of developers and C++ used by 9.118%. The two languages swap rankings from last month, when C++ was used by 9.358% of developers and Objective-C by 9.094%.

"Right from the beginning, Objective-C and C++ competed to become the de facto object-oriented programming language," Tiobe said in its monthly report. "It took quite some years before C++ could claim victory. Now Objective-C is back (thanks to the iPhone and iPad), but not as a direct competitor of C++ any more. C++ is used heavily in large high-performance systems, whereas Objective-C is mainly used in the mobile apps industry."
Tiobe's ratings are based on number of skilled engineers, courses, and third-party vendors leveraging a particular language, with rankings determined by assessments of popular search engines like Google, Bing, and Yahoo. Analyses of other sites, such as Wikipedia, Amazon, and YouTube, also are factored into the assessment. C maintained the top spot in this month's index, used by 18.331% of developers, while Java again comes in second place, used by 16.087% of developers. Rounding out the top 10 were C#, in fifth place (6.668%), followed in succession by (Visual) Basic (5.695%), PHP (5.012%), Python (4%), Perl (2.053%), and Ruby (1.768%).
