Is UIKit faster than SwiftUI?
The question is about UIKit
Yes, UIKit is generally faster than SwiftUI. UIKit is faster in terms of performance and responsiveness, particularly in complex applications or where highly customized interactions are needed. UIKit is a mature, battle-tested framework that’s been hugely optimized for performance on iOS, particularly in cases when detailed UI and animation control is necessary. It does also provide low-level fine-tuning, which can yield better performance in specific scenarios.
SwiftUI, being a declarative framework, is drafted for speed and ease of development, though at some cost concerning performance in complicated UIs. If an application is big and performance-critical, it’s better to stick to UIKit, while SwiftUI would serve well for rapid development and prototyping.
