I can't delete Xcode 7 beta off of my mac
I installed Xcode 7 beta before the actual one came out so that I could use a few certain features.
Time has gone by and I haven't been on Xcode at all and now I see that Xcode 7 is out on the App Store.
I didn't install Xcode 7 beta through the App Store so now I AM able to install the App Store Xcode 7.
Thats great, except I don't want my old Xcode 7 BETA still on my mac wasting 8GB of space.
I've tried dragging and dropping it into my trash but it says, "The item 'Xcode-beta' can't be moved to the Trash because it's open."
I don't have anything Xcode-y open anywhere on my mac, I've even tried restarting and moving it to Trash again but nothing.
I've tried googling a lot of answers to this problem but haven't found any.
Please help, I really need to get this 8 GB of crap off of my mac.
Thanks
