The foundation of Apple’s mobile operating system is built upon a combination of programming languages. While Objective-C served as the primary language for many years, Swift has progressively become the dominant language for iOS development. C and C++ also play a significant role, particularly in the lower-level system components and frameworks.
The selection of these languages offers a blend of performance, stability, and modern development paradigms. Objective-C, with its roots in C, provided a robust and mature platform for the initial development of the iOS ecosystem. The introduction of Swift brought enhanced safety features, improved syntax, and increased development speed, contributing to a more efficient development process and potentially more reliable applications. The continued use of C and C++ ensures optimized performance for critical system functions.
