Swift (iOS/macOS) is leading again: why are developers choosing Apple's language?
The annual Stack Overflow developer survey is one of the most authoritative studies in the IT world. In 2024, the results once again confirmed Swift's status as the most loved and desired programming language among the professional community. For several years, Swift has consistently been in the top 3, and in the latest report it took first place in the "Most Loved" category, ahead of Rust, TypeScript, and Python.
Why has Swift become so beloved by developers?
Swift is not just a language for creating applications for iOS and macOS. It is a modern, safe, and expressive ecosystem that is constantly evolving. Here are the key factors of its success according to survey data and analytics:
- Safety and speed. Swift was designed from the ground up to avoid entire classes of errors typical of Objective-C. Strong typing, memory management through ARC (Automatic Reference Counting), and optional types (Optionals) make code more reliable. At the same time, Swift's performance approaches that of C++.
- Modern syntax. Code in Swift reads almost like natural English. This lowers the entry barrier for beginners and increases productivity for experienced developers. Functional capabilities (map, filter, reduce) and protocol-oriented programming make code concise.
- Apple ecosystem. Swift is the primary language for all Apple platforms: iOS, macOS, watchOS, and tvOS. With the release of SwiftUI, interface development has become declarative and intuitive, further simplifying the creation of complex applications.
- Open source. Since 2015, Swift has been an open-source project. This has attracted not only Apple developers to the community but also server-side engineers (through projects like Vapor and Kitura).
- Active community. Stack Overflow records not only love for the language but also high activity: questions about Swift receive quick and high-quality answers, and the number of new libraries and frameworks is growing exponentially.
What do the numbers say?
According to the Stack Overflow 2024 survey, more than 70% of developers who already use Swift want to continue working with it next year. This is the highest "retention" rate among all languages. Notably, Swift is also in the top 5 languages that developers would most like to learn. For comparison, the share of those "loving" Swift is significantly higher than that of Java or JavaScript, despite the latter's greater overall popularity.
Prospects for Swift in 2024-2025
Experts note that the growth in Swift's popularity is directly linked to the expansion of the Apple ecosystem and the emergence of new technologies:
- Swift 6.0 — improvements to concurrency mechanisms (actor model) and further compiler optimization are expected.
- Swift on the server — projects like Vapor and Hummingbird are gaining momentum, making the language a versatile tool (Full-Stack on Swift).
- AR/VR — with the release of Apple Vision Pro and the RealityKit framework, demand for Swift developers for spatial computing will sharply increase.
If you are not yet familiar with Swift, now is the time to pay attention to it. The language combines the power of systems programming with the simplicity of scripting languages, and its future on Apple platforms looks bright. As Stack Overflow surveys show, developers are not wrong in their love — Swift truly makes the process of creating programs fast, safe, and engaging.
Conclusion: Swift
