When creating applications for Apple devices, developers look for tools and technologies that allow them to build high-quality products efficiently. With the emergence of SwiftUI in 2019, Apple introduced us to an innovative and straightforward way to design user interfaces. Despite the advantages that SwiftUI offers, UIKit, the classic approach, remains valuable for Apple app developers. In this post, we will analyze why both approaches remain relevant and how to choose the most suitable one for your projects.

Compatibility with older devices: When choosing a tool to design user interfaces, it’s essential to consider whether it will work on older devices. SwiftUI requires a relatively recent operating system (iOS 13 or later), limiting its use on older devices. On the other hand, UIKit works on older versions of iOS, allowing applications to reach more users.

Experience and solidity: UIKit has been the main tool for creating Apple applications since 2007, and as a result, it has been tested and improved over the years. Although SwiftUI is promising and constantly evolving, it is still relatively new and may present problems in certain cases. For large or complex projects, the solidity and experience of UIKit can be crucial.

Variety of options and features: UIKit offers a wide range of options and features not available or not yet fully developed in SwiftUI. This allows developers to take full advantage of the capabilities of Apple devices and create more powerful and customized applications.

Resources and community support: Due to its longevity, UIKit has a wealth of resources and solid community support. Although SwiftUI is rapidly gaining popularity, UIKit still offers a wider community, with an abundance of tutorials, additional libraries, and discussion forums.

Conclusions

While SwiftUI is undoubtedly an exciting and rapidly evolving technology, we should not underestimate the value and importance of UIKit in the world of Apple applications. By evaluating the specific needs of your project, such as compatibility with older devices, the solidity of the tool, and the required features, you can make an informed decision about which approach is most suitable for you.
