   let udid = UIDevice.current.identifierForVendor?.uuidString
   let name = UIDevice.current.name
   let version = UIDevice.current.systemVersion
   let modelName = UIDevice.current.model
   print(udid ?? "")    // D774EAE3F447445F9D5FE2B3B699ADB1
   print(name)          // iPhone XR
   print(version)       // 12.1
