One request after another - returns no data

When I try to make a couple of request one after the other (2-3 seconds in between the requests) (Go back and forward between screens in my iOS app (Fetch method called in ViewDidAppear)). The first request correctly returns data, but the second request doesn’t.
I am fetching my data with the following method:



        Backendless.sharedInstance().data.of(Group).find({ (objects) in


            guard let someGroups = objects.data as? [Group] where someGroups.count > 0 else {
                return
            }


            self.groups = someGroups


            self.tableView.reloadData()


            
        }) { (error) -> Void in
            // MARK: Show Error
   
        }

How would I manage to fix this?

We’ve found the solution - please update Backendless SDK from CocoaPods (3.0.17 release) or from github (CommLibiOS and backendless).
