Just hang around the swamp long enough and they will come for you. :)

If you've only leveled your clubs skill, and you're wandering around with a bronze mace... hit them with a torch, instead; it does more damage. Yes, really. They're resistant to blunt, pierce, and slash... but fire works wonderfully.

That being said, fire arrows are the best; damaging them at range means they don't get to hit you back.

Also, they're completely immune to frost and poison; let superior knowledge inform your attack strategy. https://valheim.fandom.com/wiki/Wraith
