    Hi,

    I'm trying to work with the StreamingAssets on iOS, but I'm getting the following error when trying to do so:


    System.Exception: /var/containers/Bundle/Application/013A63C1-FA74-4308-8351-ACAD8AF8B23E/nogameqa.app/Data/Raw/AssetBundles/AssetBundles.json, error: Cannot connect to destination host at

    Also notice that from what I see, if I'm trying to use Application.persistentDataPath for saving/reading other files from the persistent location (not the streaming assets), I'm getting different GUID for the application

    /var/mobile/Containers/Data/Application/3AAA10F0-8990-421F-A4BE-5283DA433212/Documents/somefile.bin


    Could the difference between the application GUID can give us a clue for the error that I'm getting?
    What can cause the difference in the GUID between Application.persistentDataPath and Application.streamingAssetsPath?

    Thanks,
    Tomer

    Solved it by adding the prefix file://
    Like this:


    StreamingAssetsBundlesFolder = Path.Combine(Application.streamingAssetsPath, "AssetBundles");

    if (!StreamingAssetsBundlesFolder.Contains("file://")) // Otherwise it doesn't work
    {
    StreamingAssetsBundlesFolder = $"file://{StreamingAssetsBundlesFolder}";
    }

    This expected, UnityWebRequest/WWW take URI as parameter, not path.
