Someone please remember this show!
It was an english or Australian show, as the actors had accent, where there was a family who moved into a new house and I think that the house they moved into used to be this girl's.. who is also in the show but as a ghost?

Basically the show was about the boy hanging out with this ghost girl.. coming of age preteen

And there was something about a swing... I think she might have been swinging when she died?

Thank you in advance!
