Hello Najeeb,
It is great to hear you are thinking of visiting Ireland!
To be able to visit Ireland with a UK visa, the visa needs to be endorsed with the letters 'BIVS'. As your visa doesn't have them, it won't be enough for you to enter Ireland. Therefore, I recommend you to contact the UK embassy in Sweden and ask if there is a way to fix this. However, one of the conditions of this endorsement is that you must be living in India at the time of the application, which is why you might need to get a separate visa to visit Ireland. You can read more about the conditions for this visa
here.Hopefully you can get this solved in no time.
Best,
David.
