When using the animation, the CPU usage rises to around 20-25%.

I'm new to developing with SwiftUI and I created a Pomodoro app for macOS that runs in the menu bar. I added 4 animations and when the user selects the snow animation, it starts snowing on the screen. But the app uses 20%-30% of the CPU and has high energy consumption. I can't reduce it and I couldn't find a solution.

// snow animation
import SwiftUI

struct SnowflakeView: View {
    @State private var flakeYPosition: CGFloat = -100
    @State private var isAnimating = false
    
    private let flakeSize: CGFloat = CGFloat.random(in: 10...30)
    private let flakeColor: Color = Color(
        red: Double.random(in: 0.8...1),
        green: Double.random(in: 0.9...1),
        blue: Double.random(in: 1...1),
        opacity: Double.random(in: 0.6...0.8)
    )
    private let animationDuration: Double = Double.random(in: 1...3)
    private let flakeXPosition: CGFloat = CGFloat.random(in: 0...310)
    
    var body: some View {
        Text("❄️")
            .font(.system(size: flakeSize))
            .foregroundColor(flakeColor)
            .position(x: flakeXPosition, y: flakeYPosition)
            .onAppear {
               
                if !isAnimating {
                    withAnimation(Animation.linear(duration: animationDuration).repeatForever(autoreverses: false)) {
                        flakeYPosition = 280 + 50
                    }
                    isAnimating = true 
                }
            }
    }
}

I also have how I run the animation below.

 ZStack {
                   
           ForEach(0..<10, id: \.self) { index in
                  if selectedAnimal == "Snow" {
                      SnowflakeView()
                   } else if selectedAnimal == "Rain" {
                        RainDropAnimation()
                    }else if selectedAnimal == "Leaf"{
                        LeafFallAnimation()
                    }else if selectedAnimal == "Confetti"{
                         ConfettiAnimation()
                   }
                    
       

       }
                            
                        
                }
