title: NWPathMonitor path always none on watchOS
body: <p>I am using NWPathMonitor to detect if an internet connection is available:</p>
  <pre><code>private let nwPathMonitor = NWPathMonitor()
  
  func startObservation() {
      nwPathMonitor.start(queue: .main)
  }
  
  func update() {
      guard nwPathMonitor.currentPath.status == .satisfied else {
          return
      }
  
      // ...
  }
  </code></pre>
  <p>This works fine on iOS, but on watchOS <code>nwPathMonitor.currentPath</code> will always be <code>none</code>. I am testing on a real device. Is this intended behaviour, or are there extra steps necessary to make this work on watchOS?</p>
