What new tools or technologies have you recently mastered?

Recently, I mastered SwiftUI — a modern framework for iOS UI development. It allows creating interfaces declaratively, simplifying and speeding up development. For example, with SwiftUI, you can quickly create adaptive interfaces that automatically adjust to different screen sizes.

I also studied Combine — a framework for reactive programming that helps work with asynchronous data streams, useful for handling network requests and user events.

Example of simple SwiftUI code:

import SwiftUI

struct ContentView: View {
    @State private var count = 0

    var body: some View {
        VStack {
            Text("Tapped \(count) times")
            Button("Tap me") {
                count += 1
            }
        }
        .padding()
    }
}
