Xcode-beta can not be opened while it is being updated

Question

I'm using Xcode beta 8.1 beta 2 for development.
It was working fine for me.
But suddenly, it closed and I tried to open it prompted me this message:

Xcode-beta can not be opened while it is being updated.

When will it be resolved?

Answer 1

Open activity monitor (/Applications/Utilities/Activity Monitor.app), switch to the CPU tab and search for storedownloadd. If that process is present and you aren't downloading anything using the Mac App Store, you can kill it.
