I'm also facing same issue.This is happened because of your permissions override. I completely uninstall the exist xcode Applications. I installed from the start.

1. You should remove these files from your machine.

~/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Caches/com.apple.dt.Xcode
~/Library/Developer/Xcode
~/Library/Developer/CoreSimulator  

2. restart your computer
