Fuse version 1.1.0 (build 13808)  
OS: macOS Sierra 10.12.5

```auto
git clone https://github.com/poul-kg/MapViewExample
cd MapViewExample
fuse preview -t=iOS
Run app in XCode with iPhone attached
on iPhone I see "Loading, Starting Project" forever

```

MainView.ux

```auto
<App>
    <ClientPanel>
        <NativeViewHost>
            <MapView Latitude="59.911567" Longitude="10.741030" Zoom="10">
                <MapMarker Latitude="59.911567" Longitude="10.741030" Label="Fuse HQ"/>
            </MapView>
        </NativeViewHost>
    </ClientPanel>
</App>

```

MapViewExample.unoproj

```auto
{
  "RootNamespace":"",
  "Packages": [
    "Fuse.Maps",
    "Fuse",
    "FuseJS"
  ],
  "Includes": [
    "*"
  ]
}

```

Also I have the following messages in XCode

Hi Pavel,

we have seen the `MobileGestalt` thing before, and it’s likely related to your Apple ID / XCode setup.

The best we have is [this forum post](https://www.fusetools.com/community/forums/bug_reports/cameraview_not_working?page=1&highlight=1c3755bc-e641-4aea-9ae7-15684e517856#post-1c3755bc-e641-4aea-9ae7-15684e517856) so if you could check all your Apple-related settings and figure out what causes the issue, that would be of great help.

Somehow it just started working after I came home.  
I tried to add GeoLocation Module and try few GeoLocation examples from documentation.  
Then again tried MapView and it started working.

Also I’ve added the following to .unoproj file

```auto
"iOS": {
        "PList": {
            "MKDirectionsApplicationSupportedModes": [
                "MKDirectionsModeCar",
                "MKDirectionsModeBus"
            ],
            "UIRequiredDeviceCapabilities": [
                "location-services"
            ]
        }
    }

```
