title: How to access/modify parent view variable in subviews?
body: <p>I have parent view container which holds multiple subviews.</p>
  <pre><code>struct Person {
    var name: String
    var lastname: String
  }
  
  class ParentContainer: UIView {
   var person = Person(name: &quot;Vish&quot;, lastname: &quot;Deshmukh&quot;)
   let child1 = ChildView1(person)
   let child2 = ChildView2(person)
   let child3 = ChildView3(person)
  }
  </code></pre>
  <p>How should I make sure if any of the child change <code>person</code> object, reflect that value everywhere including other child views and parent Container view?</p>
