What tools and components do you use to create and manage interfaces in UIKit?

In UIKit, the following main tools and components are used to create and manage interfaces:

• UIView and its subclasses: Basic building blocks of the interface, such as UILabel, UIButton, UIImageView, etc.
• UIViewController: Controllers that manage views and their lifecycle.
• Storyboard and XIB files: Visual editors for designing interfaces using Interface Builder.
• Auto Layout: A system for creating adaptive interfaces using constraints.
• Stack Views (UIStackView): Simplify the layout of elements in horizontal or vertical stacks.
• Navigation Controller and Tab Bar Controller: For organizing navigation between screens.

Example of creating a button programmatically:

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

// Auto Layout setup
button.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    button.centerXAnchor.constraint(equalTo: view.centerXAnchor),
    button.centerYAnchor.constraint(equalTo: view.centerYAnchor)
])

@objc func buttonTapped() {
    print("Button pressed")
}
