Unable to access application container from iPad running on iOS 10 beta

I am not able to download app container using xcode for my application on iOS 10 beta 4. I am using later xcode (beta 4). When I connect my device and go to Device in xcode, I am able to see my app listed but when I click on download container I get below error:

Is there anything to do with my app setting or device setting. How can I get my app data for iOS10 beta 4.

How do I download containers in Xcode?

The only official way to do that is via this Xcode's window, however I find it clumsy because you need to open the window, select the application, click the gear icon, select “Download container…” in the popup menu, select where to save it, wait and after a while a new Finder window will be helpfully open, but stealing ...

Further testing indicates this could be related to the fact that only containers from debug builds are downloadable. Versions built as Release/Distribution builds don't seem to allow the application container to download.
