For December, Objective-C, which is commonly used to build iOS and Mac OS apps, ranked No. 3 and C# ranked No. 5 on the TIOBE Index of the most popular programming languages.

Tiobe believes “chances are high” that C# could replace C among the top three languages in the index. Also trending upward is C++, its rating rising 1.01 percentage points in the past year.

Keep an eye on Dart and TypeScript in 2024, TIOBE Software CEO Paul Jansen suggests. TIOBE Software has declared C# the programming language of 2023 based on its long-running popularity index.
