How to STOP Animation().repeatForever in SwiftUI

Question

In SwiftUI I am trying to start and STOP an animation with a button. I can\'t find a method within SwiftUI that lets me stop an automation. In Swift 4 I used to say \"star

Answer 1

The following should work, moved animation into overlay-only and added conditional to .default (tested with Xcode 11.2 / iOS 13.2)

Button("Start", action: { self.start.toggle() })
    .font(.largeTitle)
    .padding()
    .foregroundColor(.white)
    .background(RoundedRectangle(cornerRadius: 10).fill(Color.green))
    .overlay(
        RoundedRectangle(cornerRadius: 10)
            .stroke(Color.green, lineWidth: 4)
            .scaleEffect(start ? 2 : 0.9)
            .opacity(start ? 0 : 1)
            .animation(start ? Animation.easeOut(duration: 0.6)
                .delay(1) // Add 1 second between animations
                .repeatForever(autoreverses: false) : .default)
    )
