title: Swift - MultipeerConnectivity Type does not conform to protocol
body: <p>I am trying out <a href="http://www.appcoda.com/chat-app-swift-tutorial/" rel="nofollow noreferrer">this tutorial</a> and having some problem with the code:</p>
  <pre><code>class MPCManager: NSObject, MCSessionDelegate, MCNearbyServiceBrowserDelegate, MCNearbyServiceAdvertiserDelegate {
  </code></pre>
  <p>I got an error:</p>
  <blockquote>
  <p>Type 'MPCManager' does not comform to protocol 'MCSessionDelegate'</p>
  <p>Type 'MPCManager' does not comform to protocol 'MCNearbyServiceBrowserDelegate'</p>
  <p>Type 'MPCManager' does not comform to protocol 'MCNearbyServiceAdvertiserDelegate'</p>
  </blockquote>
  <p>But I download the sample file it did not get the same error. Which part had I missed out?</p>
