I re-used some of the code snippets from your code gen projects in order to try and retrieve data from my Alerts table in Backendless and display the data in a UITableView. However, no data is populating my ViewTable even though there is data in the collection viewable when I run an NSLog. I can’t see where I am going wrong. It seems that the table code is correct since when I create a test array and use that as the data, it populates the table as expected. I’ve been trying to figure this out for the past couple of hours and it probably needs a next set of eyes on it. See my code below.

#import "Fall2013IOSAppAppDelegate.h"
