When developing an iOS app, selecting the right UI framework can make a significant difference in development speed, app performance, and user experience.
SwiftUI is Apple’s declarative UI framework introduced in 2019, designed for rapid development across Apple's ecosystem.
UIKit, introduced in 2008, has been the backbone of iOS development for over a decade, providing extensive tools and resources for creating highly customized applications.
SwiftUI offers simplicity, rapid prototyping, and cross-platform development, while UIKit provides fine control, backward compatibility, and support for complex applications and custom animations.
