Asset Bundle Manager wont load assets on iOS device xcode9.2,Asset Bundle Manager Demo not loading when building to device in xcode 9.2

I'm also having problems with the latest download of the Asset Bundle Manager using unity 2017.3.0f3. i've downloaded the manager from https://bitbucket.org/Unity-Technologies/assetbundledemo/overview I can simulate the loading of assets using the pre-made AssetLoader and SceneLoader scenes in the editor... but trying both of those scenes on device doesn't load anything, I've tried doing them with On demand resources loading as on demand is what i'm aiming for with my app. Also tried without on demand. I've unticked simulate and built the asset bundles, I've also tried the local asset bundle server option but that always errors out: SocketException: No such host is known. when calling System.Net.Dns.GetHostByName(). REALLY stuck on this and its essential for me to get resources on demand as i'm trying to make a tvOS version of the app. Are there steps i'm missing? the landing page for downloading the Asset Bundle Manager simply says to enable on demand resources so would this work if i actually deployed to test flight instead of running in xcode?,I'm also having problems with the latest download of the Asset Bundle Manager using unity 2017.3.0f3. i've downloaded the manager from https://bitbucket.org/Unity-Technologies/assetbundledemo/overview I can simulate the loading of assets from bundles using the pre-made AssetLoader and SceneLoader scenes in the editor... but trying both of those scenes on device doesn't load anything, I've tried doing them with On demand resources loading as on demand is what i'm aiming for with my app. Also tried without on demand.
