However, in Tiobe's February 2020 ranking, Objective-C finally looks to be tanking on the index, reflecting the reality that developers have either switched to Swift or to some other cross-platform mobile development framework like Xamarin.
Objective-C dropped seven spots over the past month and 10 spots since Tiobe's February 2019 ranking, effectively switching places with Swift, which was ranked 20th a year ago but is now in 10th spot.
Tiobe today offered an explanation for what happened to the rankings of the two languages since Apple introduced Swift in 2014.
Tiobe argues that while Objective-C did decline rapidly in its index between 2014 and 2016, Swift's relatively slow rise was due to developers turning to cross-platform frameworks. However, it also notes Objective-C's fall to 20th took "much longer than expected".
"In 2014 Apple announced the new programming language Swift to be the successor of Objective-C. At that moment Objective-C was at position #3 in the Tiobe index, and development of mobile apps for iPhones and iPads was booming," the company explains.
"After the announcement Objective-C dropped from 12% market share in 2014 to 1% market share in 2016. Surprisingly, Swift grew from 1% to only 2% at that same time. The other 10% was consumed by other programming languages that appeared to be compilable for multiple mobile platforms."
