Xcode update stuck at waiting

I'm trying to update to Xcode 7.1. But this what I get. 😟

I tried restarting the system. No use.

I checked in Console. And, I can see a lot of these:

22/10/15 09:42:31.000 kernel[0]: Sandbox: storeaccountd(2111) deny(1) file-write-create /Users/saneef/Library/Caches/com.apple.spotlight
