In the past I have used a bolt; not threaded into, but sat into the hollow of the axle, to give a good flat perch to hammer against. If you chew up the head of the bolt just exchange it and keep going. A nice big hammer and as others have said lay the frame against some timber so that your force isn't being absorbed by the frame flexing away.
Stay patient and work at it over a couple of days cycling between heat, lube and a good few hits. Typically once it starts moving it all happens reasonably quickly.

Agree with this mostly.
Will free up eventually without destroying the swingarm bolt or doing any other damage.
You shouldnt be beating on it so hard that you are ruining the threads or mushrooming the bolt.
Not just to save that swingarm bolt.
But because when you compress the threads and mushroom the end of the bolt or slightly bend it---
then it will only slide through the bearings to that point.
And then you are really screwed.
