XCode 10 shows no simulators or devices

I just reinstalled XCode 10 and now navigating to XCode -> XCode -> Open Developer Tool -> Simulator -> Hardware -> Device -> Manage Devices shows no devices or simulators:

Does anyone know what might cause that behavior, or what I can do to install a simulator version (e.g. iOS 6s)? Any help would be greatly appreciated!

Solution

  • So this machine had a previous version of XCode installed, and had some legacy simulators that were left over from that earlier XCode installation. Step one was to remove those simulators:

    xcrun simctl delete unavailable

    Then I manually created a new simulator:

    xcrun simctl create duhaime-6s com.apple.CoreSimulator.SimDeviceType.iPhone-6s com.apple.CoreSimulator.SimRuntime.iOS-12-0

    Those arguments are: xcrun simctl NAME DEVICE_TYPE RUNTIME. You make up the simulator name, and can select a device type and runtime from the list of options displayed if you run xcrun simctl list. After creating the simulator, you can start it:

    xcrun simctl boot 4A6368C3-A94C-4D83-8AA3-9E9900ABCC74

    That GUID / simulator ID will be displayed if you rerun xcrun simctl list.
