-

excuse me if explained somewhere in swift, know simple can't find answer anywhere.

so problem have class in parse called "groups" has "title" object in it. in code below, creating new class called "rankeditems" has it's own objects. 1 of objects "groupowner" , objective here assign pointer "title" object in "groups" class.

my code listed below. have wrong syntax in line of code attempts create "groupowner", have been trying figured leave in placeholder.

can point me in right direction how should create "groupowner" pointer object in "groups" class? thanks!

 // add parse group object         var itemrank:pfobject = pfobject(classname: "rankeditems")          itemrank["itemname"] = newitem         itemrank["groupowner"] = pfobject(withoutdatawithclassname: "groups", objectid: "title")         itemrank.saveinbackgroundwithblock {             (success: bool, error: nserror!) -> void in             if (success) {              } else {                 // there problem, check error.description                 println("error adding group parse")             }         }          self.typeditems.append(newitem)          self.tableview.reloaddata()       }))
