Apple's Objective-C programming language eventually left Tiobe's top 20 most popular programming languages list, but a "dinosaur" language has seen an unexpected surge in popularity.
Objective-C, the programming language supplanted by Apple's Swift for the development of iOS and macOS applications, has finally left the top 20 most popular languages, according to the April 2021 edition of the Tiobe Programming Index Community. Although Apple launched Swift seven years ago, Objective-C continues to feature in Tiobe's list of the 20 most popular languages in the world. As a reminder, the programming language occupied third place in the index in 2014, when Swift arrived.
Tiobe provides software quality analysis to businesses and bases its rankings on the share of total searches for each language according to several popular search engines. Over the past year, Objective-C has slowly but steadily fallen into this list. Tiobe hypothesized that Objective-C has remained popular in part because adoption of Swift has slowed, as mobile app developers turn to languages that can be used to build apps on multiple platforms.
Swift, meanwhile, fell to 15th place in Tiobe's index today, down from 11th place in April 2020.
