objective c - simulator name is shown with id instead of os name in Xcode 6.2

Question

I've installed additional ios simulators(7.1) just after installing Xcode 6.2 and now the simulator names look like this:

How do I change the names?

Answer 1

Xcode uses the device version to disambiguate devices with the same name. If two devices have the same name and version number, it will show the devices' UDIDs.

You have 4 of each of all your device types, so I suspect that some of them are for the same iOS version. You should delete some of the duplicates. Check out

xcrun simctl list

and

xcrun simctl delete

or go to Windows>Devices in Xcode to delete or rename your devices.
