Reviews for Swift
Hear what real users highlight about this tool.
Swift earns glowing praise for speed, safety, and tight alignment with Apple platforms. Makers of Sugar Free: Food Scanner highlight strong performance and smooth ecosystem integration, while makers of Eight Sleep report better reliability, faster iteration, and easy adoption of Widgets, Watch, and Siri. Makers of Omi note rapid delivery of buttery-smooth native apps. Users commend clean, modern syntax, SwiftUI’s productivity across Apple platforms, and helpful typing and concurrency. Downsides are modest: tooling feels Apple-centric and the broader ecosystem is smaller than JavaScript or Python.
This AI-generated snapshot distills top reviewer sentiments.
Swift is my favorite programming languages and helped me fall in love with programming
Frontend for FitDM. Pretty solid.
Already worked with a lot of programming languages (C, C++, ObjectiveC, Java, JavaScript), but Swift is definitely one of the best (if not THE best). The only small downside is that generics are really extremely "typed", but even this improved a lot over the last few years. The best things about Swift: safe optionals, good error handling and Swift concurrency.
🐾 Hi everyone! 👋 We built Pawbit — a Swift-based iOS habit tracker — to make building good habits simple, fun, and surprisingly cute!
The application was originally built using Flutter, but we ultimately transitioned to Swift to take full advantage of Apple APIs that are central to the project's functionality.
Swift has become one of my favorite languages to work with. It strikes a nice balance between readability and performance — modern syntax without sacrificing speed. The strong typing and safety features help avoid common pitfalls, while still feeling expressive and fun to write.
Swift makes building performant, safe, and modern apps a breeze. Compared to other languages, it feels cleaner, faster to write, and much more fun to work with - which is exactly why GeoCeptor exists today. Its multiplatform functionality also helped me add a macOS version without too much hassle.
Swift’s modern language and UI tooling enabled even a first-time iOS maker like me to ship a fully featured app.
Swift let us move from prototype to App Store release fast. We used RealityKit to build a fully spatial environment, SwiftUI to anchor a responsive HUD directly to the headset, and AVFoundation to handle audio with minimal overhead. The result was a Vision Pro title with native-level performance, smooth gameplay, and zero reliance on external engines. Swift
Swift strikes the perfect balance between safety and performance. It helps build robust iOS apps quickly, and the community and tooling make it easy to scale clean, maintainable code. It’s our go-to for all Apple platforms.
For an app like ThunDroid, where user trust, stability, and data security are the absolute foundation, Swift was the only choice. Its modern emphasis on safety—with strong typing and features that prevent common crashes—is a game-changer compared to older languages. It allowed us to write clean, high-performance, and incredibly reliable code, ensuring the app is a stable and safe space for our users when they need it most.
Apple's modern, safe programming language with excellent performance and readability. Perfect for iOS development with powerful features like SwiftUI integration and memory safety.
Clean syntax and powerful features like Combine made building a responsive timer straightforward. The type safety caught bugs early, and SwiftUI made creating smooth animations for the interval transitions surprisingly simple.
