You can use the following function for creating the UUID:

func getUniqueDeviceIdentifierAsString() -> String { var appName: String? = (Bundle.main.infoDictionary?[(kCFBundleNameKey as? String)] as? String) var strApplicationUUID: String = SSKeychain.password(forService: appName, account: "incoding") if strApplicationUUID == nil { strApplicationUUID = UIDevice.current.identifierForVendor.uuidString SSKeychain.setPassword(strApplicationUUID, forService: appName, account: "incoding") } return strApplicationUUID }
