The Parse documentation for adding properties and methods on PFObject subclasses conveniently skips the Swift syntax in their sample code listing just the Objective-C syntax
I had this same problem. Had to add @NSManaged to the properties I wanted saved:
class Armor : PFObject, PFSubclassing {
@NSManaged var displayName: String
class func parseClassName() -> String! {
return "Armor"
}
}
var armor = Armor.object()
armor.displayName = "Iron Clad"
Hopefully this is resolved in the next update.
