title: How to alter a View in SwiftUI
body: <p>How can I modify a View after using it?
  E.G:</p>
  
  <pre><code>var body: some View {
      Button (action: {
          // Code to move button's position. self.offset(x:y:) doesn't work, Xcode says 'result of call to offset is unused'
      }) {
          Text("How to I alter the colour of this text?") // Change colour somewhere else in my script
              .background(Color.black)
  
      }
          .frame(alignment: .leading)
  
  }
  </code></pre>
  
  <p>I need to modify a View after it has been instantiated. Because everything is a View, from the <code>.frame</code> to the <code>.background</code>, shouldn't I need to reference/delete/modify/add them to the stack?</p>
