If somebody facing similar issue with Xcode 9.1
Open directory:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Create new folder "11.2 (15C107)" (or "10.3 (14E269)" for older versions, depends on what exactly are you missing)
Paste files from provided google drive folder
11.2 (15C107) (or 10.3 (14E269) if you need older files)
Restart Xcode
For other iOS versions you may check @Sour LeangChhean 's answer
Keep in mind, that some day you will need to upgrade your Xcode anyway :)
