title: Place cursor at the end of UITextView under UITest
body: <p>This is how I clear <code>UITextFields</code> and <code>UITextViews</code> in UITests.</p>
  
  <pre><code>extension XCUIElement {
  
     func clear() {
  
        tap()
  
        while (value as! String).characters.count &gt; 0 {
           XCUIApplication().keys["delete"].tap()
        }
     }
  }
  </code></pre>
  
  <p><strong>Example of use:</strong></p>
  
  <pre><code>descriptionTextView.type("Something about Room.")
  descriptionTextView.clear()
  </code></pre>
  
  <p>If I run UITests, it always tap at the beginning of UITextView.</p>
  
  <p>How to tap at the end?</p>
