import SwiftUI

struct ContentView: View {
    @State private var isAnimating = false
    
    var body: some View {
        VStack {
            Text("Hello, World!")
                .font(.largeTitle)
                .foregroundColor(.blue)
                .scaleEffect(isAnimating ? 2.0 : 1.0)
                .animation(.easeInOut(duration: 1.0))
                .onAppear {
                    self.isAnimating = true
                }
        }
    }
}

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