title: Make scrollbar in ScrollView always visible in SwiftUI
body: <p>I'm developing an application in SwiftUI.
  I have a horizontal scroll view which shows the scroll bar when the user taps on it. As this app is targeted more towards older users, I want to continually display the scrollbar. I couldn't find anything in the Apple documentation on how to enable this. There's an attribute called <em>showIndicators</em> which is true by default and enables the scrollbar by tapping but doesn't continually display the scrollbar. This is a simple code snippet of my ScrollView:</p>
  <pre><code> var body: some View {
      ScrollView(.horizontal) {
          HStack(spacing: 4) {
          // other stuff in the scroll view
      }   
   }
  </code></pre>
