I personally think, on the basis of his behaviour, he is guilty of both failure to appear as bailed, and the charges in Sweden.
That said I think that it is indisputable he is guilty of "Failing to attend court on time as required". On the legality of the other charges there is a good summary here -

The recent decision by "United Nations Working Group on Arbitrary Detention" may well be good for Assange but really does seem to fly in the face of the human rights of the women in Sweden.
