It’s pretty easy to accomplish this animation using the ObservableObject. Let me show you how. Use the below class to display all your views one by one.

struct RFWeekdayListView: View {
	@ObservedObject var settings = UserSettings()
	var weekdays : [String] = [""]
	var parentController : SwipeController?
	init(weekdays:[String]) {
		self.weekdays = weekdays
	}
    var body: some View {
		GeometryReader { reader in
			ScrollView {
				VStack {
					ForEach(0 ..< self.weekdays.count) { pos in
						DaySwiftUIView(pos: pos, size: reader.size, delay: Float(pos), color: colors[pos])
					}
				}
			}
		}
    }
}

Display your views DaySwiftUIView using a for loop. Let’s write the actual class which does this animation. The single line of code which animates the view is

.animation(Animation .spring(response: 0.3, dampingFraction: 0.5, blendDuration: 0.5) //.easeInOut(duration: 0.5) .delay(Double(self.delay)))

Inside your swift class which is shown below, use the offset property to set the frame depending on the @Published property as shown here.
.offset(x: self.settings.removeDayView ? 0 : size.width, y: 0)

import SwiftUI

struct DaySwiftUIView: View {
	@ObservedObject var settings = UserSettings()
	private var pos : Int = 0
	private var size : CGSize = .zero
	private var delay : Float = 0
	private var color : Color = .clear
	init(pos : Int, size : CGSize, delay : Float, color: Color) {
		self.pos = pos
		self.size = size
		self.delay = delay * 0.1
		self.color = color
	}
    var body: some View {
		Text(weekdays[self.pos])
			.background(Rectangle()
				.fill(self.color)
				.frame(width: size.width, height: size.height/7))
			.animation(Animation
					.spring(response: 0.3, dampingFraction: 0.5, blendDuration: 0.5)
					//.easeInOut(duration: 0.5)
				.delay(Double(self.delay)))
			.onAppear {
				self.settings.removeDayView = true
			}
			.onTapGesture {
				self.settings.removeDayView = false
				let scores = ["position": self.pos]
				NotificationCenter.default.post(name: NSNotification.Name("dismissSwiftUI"), object: nil, userInfo: scores)
			}
			.offset(x: self.settings.removeDayView ? 0 : size.width, y: 0)
			.frame(width: size.width, height: size.height/7, alignment: .center)
    }
}

struct DaySwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
		DaySwiftUIView(pos: 0, size: .zero, delay: 1, color: .black)
    }
}

UserSettings is the name of the ObservableObject class which has a published variable. The removeDayView variable is the one which emits the changes to the view.

import Foundation
class UserSettings : ObservableObject {
	@Published var removeDayView : Bool = false
}
