    <p><strong>[UPDATED w/ SOLUTION and WORKING CODE in bottom section]</strong></p> <p>In -viewDidLoad I alloc, initWithFrame:</p> <p>Add myTextView to subView</p> <p>Set some basic properties (alignment, background color, text color, etc)</p> <p>Set default text</p> <p>The .text does not appear. myTextView appears (as indicated by background color), set breakpoint, it has a frame, memory, etc. Everything looks right. myTextView looks good, but the .text is nil. I change it, set it, update it. No matter what the .text remains nil.</p> <p>I have read the documentation over and over again. No mention of anything that I am not doing. I'm at a loss.

    1. COHave you tried avoiding this line `self.contentTextView.contentSize = size;`. Please also make sure that its not being wiped off from another part of your code.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
