Converting AnyObject to String ios Swift

I have this code YASAPIClient.sharedClient.getUserStepsOfDay(email, completionBlock: { (request, result, error, isCancelled, status) in if error != nil { error?.showServerErrorInViewController(self) } else if !isCancelled { print(result) if let myStr = result as? String { // Here, `result` is String print(myStr) } } }) in my case result is an AnyObject as you can see in screenshot I have seen several questions on SO but I am not able to convert this AnyObject to String. When I print result it gives "Optional(0)" and I want 0 instead. And my second print statement is not executing.
