UITAble view data not displaying in xcode

I followed this tutorial (http://ift.tt/2xGTrv8) which connects Xcode (Xcode 8) app to a mysql database using a web service. It works perfectly.

When i adopt the code to my personal project which also uses Xcode (Xcode8) to connect to my mysql database, the project compiles successfully but when running the project on the simulator no data is shown in the UITableView.

Checks that i have done - The console shows the data downloaded - Tested the web service and it works (returns data in json) - the database user that is related to the web service has full access to the database

Any ideas as to whats preventing the UITAbleView from showing the data?
