title: iOS UIPasterboard does not show message on device
body: <p>I want to show user message, that something was copied to UIPasterboard.</p>
  <pre><code>UIPasteboard.general.string = &quot;\(contact.numFirst)&quot;
  </code></pre>
  <p>In simulator it shows some general popup, but on device not.
  Can I do it without external libraries?</p>
