从SwiftUI中的动态数组中检索特定元素

import SwiftUI

struct ContentView: View {
    @State private var numbers = [1, 2, 3, 4, 5]
    @State private var targetNumber = 3
    
    var body: some View {
        VStack {
            Text("Numbers: \(numbers.description)")
            Text("Target Number: \(targetNumber)")
            Button("Find") {
                if let foundNumber = numbers.first(where: { $0 == targetNumber }) {
                    print("Found: \(foundNumber)")
                } else {
                    print("Not found")
                }
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
