    1. COThis worked for me. With ARC I had to use a bridge cast on the caller with CGPathApply(path.CGPath, (__bridge void *) bezierPoints, processPathElement); and inside the receiver method as NSMutableArray *bezierPoints = (__bridge NSMutableArray *)info;

    2. CONote that this doesn't give you points on the curve, just an array of vertices and control points. You really can't do anything with this array, because the information on the nature of points (moveTo vs. controlPoint) is lost. But that's a starting point. You can use wykobi to evaluate points that lie on the curve.

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).
