title: NEHotspotConfigurationManager not creating/joining hotspot
body: <p>I am trying to create/add a Hotspot configuration in iOS 11 installed device.</p>
  
  <p>My code is as follows</p>
  
  <pre><code>let hotspotConfig = NEHotspotConfiguration(ssid: "testNetwork")
  hotspotConfig.joinOnce = true
  NEHotspotConfigurationManager.shared.apply(hotspotConfig) { (configurationError) in
      if configurationError != nil {
        print("error")
        print(configurationError!.localizedDescription)
      } else {
        print("success")
      }        
  }
  </code></pre>
  
  <p>When i try to run the code. Device prompts for permissions as the following:-</p>
  
  <pre><code>"AppName" wants to join Wi-Fi Network "testNetwork"
  </code></pre>
  
  <p>But on tapping "Join", I am getting the following response</p>
  
  <pre><code>Unable to join the network "testNetwork"
  </code></pre>
  
  <p>However, on debug console "success" is getting printed.</p>
