解决方法：

• Go To Finder -> Applications -> Right Click on latest Xcode version -> select show package content -> Developer -> Platforms -> iPhoneOS.platform -> DeviceSupport -> Copy the latest version folder and paste at the same location of your old Xcode i.e in the DeviceSupport folder of your old Xcode.

• Then Restart Xcode.
