What tools and technologies do you use for developing user interfaces?

The following tools and technologies are commonly used for developing user interfaces on iOS:

• Swift and SwiftUI — a modern language and declarative framework for creating UI. Allows for rapid development of adaptive interfaces.
• Objective-C and UIKit — a traditional language and framework for UI development, used in existing projects.
• Xcode Interface Builder — a visual editor for interfaces in Xcode, where screens can be created using storyboards or xib files.
• Auto Layout — a system for creating adaptive interfaces, allowing constraints to be set for UI elements.
• Combine — a framework for reactive programming, often used together with SwiftUI to manage UI state.

Example of a simple SwiftUI interface:

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, World!")
                .font(.largeTitle)
            Button("Press me") {
                print("Button pressed")
            }
        }
        .padding()
    }
}
