I updated my Xcode to 7.1.1 (it said so in the Mac App Store).
When I click on "Open", Xcode 7.0.1 showed up instead of Xcode 7.1.1.
Do I need OSX El Capitan to run Xcode 7.1.1 ?
In the past, I had Xcode 7.1 Beta 2 installed, I wonder if that caused some files to be corrupted.
Seems like someone else had a similar problem here: Updated XCode to 7.0.1 via the app store but it still shows itself at 6.4 in the app and missing the new features
The answer there recommended deleting all copies of Xcode and reinstall from scratch.
I'll download OS X El Capitan to see if it fixes it before I decide to nuke Xcode to oblivion on my computer and redownload it all again
Updated my laptop to Mac OS X El Capitan but didn't fix it either. Xcode still start up as Xcode 7.0.1 =/
I guess it's time to nuke Xcode.
