You are missing a few steps here. I think your main mistake is this:
"Right click on Classes...Add...New File...UIViewController subclass and name it SecondViewController."
You should be adding a new UITableViewController subclass instead. It has a tableView field already and it is automatically hooked up to the first table in the xib you don't need to hook it up. You do however need to connect the delegate and the data source to the file's owner in the xib, and of course connect the file owner's view to the table .
Watch my video carefully which has
2 tables in a tab bar.
