This iPhone is running iOS 11.2 which may not be supported by this version of Xcode,iPhone手机升到11.2后真机调试出现以上提示，添加镜像包到指定路径，然后重启Xcode即可解决问题。镜像包添加指定路径：文件夹头部菜单的前往 ---> 前往文件夹 ---> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

iOS 14.5 镜像包, command + shift + G 前往文件夹 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport 将更新包解压进去即可
