Yesterday I updated Xcode 6.1.1 to Xcode 6.2 but after update when I see about Xcode it's still showing Version 6.1.1 (6A2008a). Any idea why?
Note: I already go to the App store and check it, but there is showing that it's updated and I can only open it.
回答1:
Download full 2.6 GB xcode completly and remove old one and try it . will fix your problm.Also check for OS compatibility.
回答2:
I solved it by reinstalling it.
i think the issue was i updated X-code first and then update Mac OS X.
so i remove X-code from mac and then reinstall it .

It says on compatibility: OS X 10.9.4 or later, I currently run 10.10.2 beta and prepare to upgrade to 10.10.3 beta. It said first after download that I did not have sufficient disc space, so I stopped a few processes and compacted some temporary folders, to get 10G available. From the update tab in the App Store, now the "update" button goes grey when pushing it (no messages), and nothing happens.
I even have renamed my old Xcode (6.1.1) to Xcode_old.app, but doesn't seem to help. Do I really need to download it from the developer centre again?
(I know App Store stores updates and partly downloaded files under hashed filenames somewhere in /Library)

Make sure you have the required OS. For example, xcode 6.3.2 requires Yosemite (v10.10):
