Animating Shape

I'm trying to animate a shape. The following is my code.

import SwiftUI

struct ContentView7: View {
	@State private var goingLeft = true
	@State private var goingUp = true
		
	var body: some View {
		ZStack {
			Color.green.ignoresSafeArea()
			CustomShape(quadDistance: goingUp ? 0: 60.0, horizontalDeviation: 0.0)
				.fill(Color.red)
				.ignoresSafeArea()
				.animation(.easeInOut(duration: 1.0).repeatForever(), value: goingUp)
		}.onAppear {
			goingUp = false
		}
	}
}

struct CustomShape: Shape {
	var quadDistance: CGFloat
	var horizontalDeviation: CGFloat
	func path(in rect: CGRect) -> Path {
		Path { path in
			path.move(to: CGPoint(x: -horizontalDeviation, y: 0))
			path.addLine(to: CGPoint(x: rect.maxX + horizontalDeviation , y: 0))
			path.addLine(to: CGPoint(x: rect.maxX + horizontalDeviation, y: rect.midY))
			path.addLine(to: CGPoint(x: -horizontalDeviation, y: rect.midY))
			path.move(to: CGPoint(x: -horizontalDeviation, y: rect.midY))
			path.addQuadCurve(to: CGPoint(x: rect.maxX + horizontalDeviation, y: rect.midY), control: CGPoint(x: rect.midX, y: rect.midY + quadDistance))
		}
	}
}

Well, my intension is to move the center of the convex point up and down. But the shape won't animate itself. What am I doing wrong? Muchos thankos.
