title: How can I have a Blur effect as a Background in SwiftUI?
body: <p>I want to have blur effect as background for my View, as we know, we can blur the view and what is inside, but I do't want blur content of view but I want blur background view to give a glassy blurred through effect as we know. How i can do this in SwiftUi?</p>
  <p>In other words, the under layer of view would be blurred in frame on current view which sets as background for current view.</p>
