title: How to Modally push next Screen to be full in SwiftUI
body: <p>how can I push a next SwiftUI View but present it over the full screen without swiping down feature like the Xcode 10 modal presentation.</p>
  
  <p>My current implementation, but it's not pushing onto the fullscreen (dragging down enabled and the gap at the top):</p>
  
  <pre><code>btn
  .presentation(
        !showModal.value ?
             nil :
             Popover(content: destination, dismissHandler: onTrigger ?? {})
  )
  </code></pre>
