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

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?

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.

Faced the same issue and here is the solution to open Xcode.

Go to Application folder -> find Xcode -> Right click and select "Show Package Content" -> Go to Content -> MacOS -> Double click Xcode (Unix excecutable file).

It worked for me!
