import SwiftUI

struct ContentView: View {
    @State private var rotationAngle: Double = 0
    
    var body: some View {
        Rectangle()
            .fill(Color.blue)
            .frame(width: 200, height: 100)
            .rotationEffect(.degrees(rotationAngle))
            .animation(.easeInOut(duration: 1))
            .onTapGesture {
                withAnimation {
                    rotationAngle += 90
                }
            }
    }
