Retrieving data not Working(Swift)

I am trying to retrieve data from a table in backendless, I am getting the following error.
fatal error: NSArray element failed to match the Swift Array Element type
Thank you.

Please update the latest Backendless SDK from CocoaPods (3.0.12 release) or from github. Then try again and let us know how it goes.

Thank you, Solved it, problem with the code.
