Put simply, it’s a tool for converting your Objective-C code to Swift with the click of a button. This could be applied to whole projects and not just code snippets, which means that Swiftify is aware of your project’s structure. What it also means is that Swiftify is not just a dumb tool that converts Objective-C’s messaging syntax to Swift’s dot syntax; it’s much more complex than that, with more than 4 years in development, it has reached a point where it can convert very complex Objective-C code to its Swift equivalent while maintaining the logical correctness of your code. As a matter of fact, Swiftify has become so good at its job that Apple has dubbed it The Swiftest way to Swift when it was featured on the AppStore.
Anyone familiar with Objective-C, as you probably are considering you’re reading this article, knows that its syntax is not the most common among programming languages and, therefore, produces a lot of challenges in understanding and translating its structure into code.
