    1. Navigate to

    Applications > Xcode.app > Contents > Developer > Platforms > iPhoneOS.platform > DeviceSupport

    1. Check the folder of same iOS version of your device's.
    2. If the directory is missing download support files of your iOS version from: https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases
    3. Add that to DeviceSupport.
    4. Clean Xcode
    5. Unplug and reconnect device

    When you have this kind of problem it means that device version is not supported by xCode version. While the other answer works, there is another way without having to copy the folder.
    Install the new XCode version somewhere on your Mac. Start it, connect your device, wait it is ready (check in organiser/devices). Then stop xCode.
    Now you can use your older xCode : the different versions of xCide share the same directory for the supported iOS versions.
