how can convert [string : string?] [nsobject : anyobject]!? right project using firebase backend swift app. after updated xcode 7 , swift 2.0, i got error .updatechildvalues function , image below. how can fix this? thanks! the problem values in dictionary of type string? , , contain nil . when dictionary passed objective-c code in firebase, it's converted nsdictionary . values in nsdictionary can't nil . i'm guessing self.deckname.text or self.deckdetails.text returning string? instead of string part of sdk update in xcode 7. if you're absolutely never return nil , can add exclamation point after self.deckname.text and/or self.deckdetails.text unwrap string? string . note if make bad assumption , return nil , program crash. if you're uncertain, self.deckname.text ?? "" , means "return deckname.text if it's not nil, otherwise return empty string".
