title: Connecting to external URL from WatchKit 2.0
body: <p>I would like to load some information in the <code>WatchKit</code> interface from a <code>REST</code> backoffice. Is there some fast way to execute a URL request passing by the host <code>iOS</code> app or I must concoct a specific protocol taking advantage of the bare <code>WatchConnectivity</code> functionalities?</p>
