Well spotted, that fixed it, thank you very much!
I now get a bunch of <Error>: CGContextFillRects: invalid context 0x0 errors, which makes sense since this snippet does not have something like:
CGContextRef context = UIGraphicsGetCurrentContext();
I replaced UIRectFill(selectionRect) with CGContextFillRect(context, selectionRect);
But I still get the errors, and nothing is drawn.
