    1. COWhat does the label actually show? Are you sure you are setting the value *before* accesing it?

    2. COIts weird because the label actually reads fine! Hence why i thought it was strange that it NSLogs as "Label". What exactly do you mean by setting it before accessing it? How would i do that?

    3. CO"Label" sounds like a preset value that you change later in code to something meaningful, i.e. in your tableView:didSelectRowAtIndexPath: method. But when you set the text of the label, the viewDidLoad method has probably already executed, thus you are working not with the value you want.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
