I am working on auto scroll in swiftUI by using Foreach. Its adding a divider automatically between view that can be seen into the give attached image below.

He is my complete code through you can reproduce the same issue. I have no idea why its showing the divider. I have tried with the following solution but it did’t work for Foreach Loop.
Remove top separator line in ListView

import SwiftUI

struct ColorsView: View {
    
    @State private var timer: Timer?
    @State private var offset: CGFloat = 0
    @State private var closeCount = 0
    
    let colors: [Color] = [
        .red,
        .blue,
        .yellow,
        .brown,
        .green,
        .orange,
        .purple
    ]
    
    var body: some View {
        ZStack(alignment: .topLeading) {
            
            GeometryReader { geometry in
                    autoScroller(geometry: geometry)
