        This approach requires you to utilize [**ReplayKit**](https://developer.apple.com/documentation/replaykit), **Broadcast Upload Extension**, other Apple video frameworks and the **ZoomVideoSDKScreenShare** framework.
      </td>
      <td>
        This approach requires you to utilize the **ZoomVideoSDK** framework.
      </td>
    </tr>
    <tr class="odd">
      <td>
        This method of sharing is highly optimized, as it is a native operating system level implementation provided by Apple.
      </td>
      <td>
        This approach is simpler to implement but it has optimization limitations.

        It is not encouraged to use this method for complex views.
      </td>
    </tr>

Depending on your use case, you may choose either of these options to
