    1. COWhat is your exact question? What are the exact problems that you are encountering? Do your code currently works? If not, which error do you get?

    2. COThanks for responding, Paul. My code works perfectly. I need to know how to take it to the next level. Let me try to be more precise. I want to call a specific video from an array that corresponds to the data in the cells array. (The video called depends on what cell the user chooses.) Then, I want to display it in a view view controller. I know it's possible to do this in story board by hard coding each cell to a view. But that seems like a clunky way to develop. I will have 15+ videos. I don't want 15 view controllers. I want one controller dynamically populated with a video from an array.

    3. COUPDATE: I have the segue to the detail view controller working. How do I load the videos into it?

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).
