I have an array of SwiftyJson data that I have declared and filled it with data .The code I\'m using to fill the hoge array is this : self.hoge = JSON(data: data!)
self.hoge should be a Swift Array (which is mutable if declared as var) or casted to a NSMutableArray. If it is of Array type use append. If casted to an NSMutableArray use self.hoge.addObject(yourObject).
