Have Swan received public money to build private flats?

On Swan's website, singing their own praises for their plans, it is stated that:

"Swan has received public subsidy from the Housing Corporation to re-develop the club and build flats for affordable rent and shared ownership."

However, we now know that Swan's latest planning application is to put up 6 private residences, not social or affordable flats. What kind of funds did Swan receive? Did it go towards the purchase of the land? Has the money been repaid?
