Getting two different device IDs from same iphone

I am getting different UDIDs for my iphone when i get it from itunes and programatically like this 

UDID:String = UIDevice.current.identifierForVendor!.uuidString

Basically im trying to acquire a unique identifier for my iphone just like we have mac address for android phones.

one easiest way is to solve this issue by storing the identifierForVendor in keychain. even if you uninstall app ,value for the key remains same and its unchanged. many third party libraries available to perform this . one of them https://github.com/jrendel/SwiftKeychainWrapper.

func getGlobalUniqueIdentifierFromKeyChain()->String{

    let retrievedString: String? = KeychainWrapper.standard.string(forKey: "DeviceId")

    if  retrievedString == nil{
        if let deviceKey  = UIDevice.current.identifierForVendor?.uuidString{
            let _ = KeychainWrapper.standard.set(deviceKey, forKey: "DeviceId")
        }
    }

    if let globalID = KeychainWrapper.standard.string(forKey: "DeviceId"){
        return globalID
    }else{
        return UIDevice.current.identifierForVendor?.uuidString ?? ""
    }
}
