在SwiftUI中使文本跳动

import SwiftUI

struct ContentView: View {
    @State private var scale: CGFloat = 1.0
    
    var body: some View {
        Text("Hello, World!")
            .font(.largeTitle)
            .scaleEffect(scale)
            .animation(
                Animation.easeInOut(duration: 1.0)
                    .repeatForever(autoreverses: true)
            )
            .onAppear {
                self.scale = 1.2
            }
    }
}

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