This question already has an answer here:
So I'm trying to update from Xcode 7.0.1 to Xcode 7.1 from the App Store. Xcode 7.1 is one of the my available updates. I use the latest EL Capitan 10.11.1. I click the UPDATE button for Xcode 7.1 it says "waiting" and PAUSE then a second later it goes back to UPDATE and nothing installs nothing updates, it's not telling me that I have something else open, which I don't. Is something wrong with App store now? Is there an alternative way to update my Mac apps?
