问题
I opened Xcode and suddenly I found the simulator devices duplicated. I found a similar question 1 but that's not my case, I'm using the latest SDK and a clean Xcode installation. Screenshot in the link bellow. Any ideas?
1 iOS Simulator devices listed twice in Xcode run destinations list

You can delete the duplicates that you don't want from Xcode's Devices window (Window -> Devices) or from the command line using 'xcrun simctl delete [UDID]'
