What advantages does UIKit provide compared to SwiftUI in interface development?

UIKit offers several advantages over SwiftUI, especially in terms of maturity and control over the interface:

• More mature and time-tested technology. UIKit has been around since iOS 2, has a rich ecosystem, numerous third-party libraries, and extensive documentation.
• Flexibility and control. UIKit allows detailed management of view lifecycle, animations, and interactions, which is important for complex or custom interfaces.
• Support for older iOS versions. If the app needs to run on iOS versions below 13, UIKit is the only option.
• Imperative programming style. For developers accustomed to the traditional approach, UIKit may feel more familiar.

Example of creating a button in UIKit:

let button = UIButton(type: .system)
button.setTitle("Press me", for: .normal)
button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
view.addSubview(button)

While SwiftUI uses a declarative style, UIKit provides more control over each step of interface creation.
