One of the most significant aspects of Swift that impressed us was its emphasis on [protocols](https://docs.swift.org/swift-book/documentation/the-swift-programming-language/protocols/). In Java, we relied heavily on inheritance, which can lead to complex class hierarchies and tight coupling. Swift’s approach of protocols and generics promotes modularity and reusability by allowing classes, structs, and enums to share common protocols, enabling a more flexible and scalable codebase. This shift in mindset encouraged us to think in terms of behaviors rather than concrete classes, resulting in cleaner and more maintainable code.

Safety is another area where Swift takes a distinctive approach compared to Java. For example, Swift’s optional type and safe unwrapping mechanisms eliminate the need for null checks everywhere, reducing the risk of null pointer exceptions and enhancing code readability. This safety-first approach ingrained throughout Swift’s language design, whether it is deterministic deallocation, copy-on-write (CoW), or value type, makes it inherently less prone to runtime errors.

Swift's async/await support is a nice addition, streamlining how we handle async tasks. Earlier managing async operations often involved complex callback patterns or external libraries. Swift’s async/await syntax simplifies this process, making it more intuitive and less error-prone. We can now write async code that reads like sync code, leading to more readable, testable, and maintainable concurrency handling—especially critical in high-load, multi-threaded environments.

Our Swift implementation has run smoothly and efficiently in production, making it worth the effort we put into this migration. In addition to outperforming our previous Java-based application, Swift delivered better performance consistency, enhanced safety features, and robust reliability — all while requiring fewer resources by utilizing memory and CPU efficiently. With fewer lines of boilerplate code and more flexible design patterns that we used, we look forward to simplified maintenance of our application. Swift was a powerful choice for building fast, resilient, and maintainable applications in our high-demand environment.
