Don't use SafeArea inset on iPhone X for first UITableViewCell

Question

I have a UITableView and the first row is used as a sort of header cell with a full bleed background image and other elements. For this cell I do NOT want to use the SafeArea and I want the UIView to expand all the way to the edge of the screen. Currently I get this:

I have tried to set this manually for the cell:

if (@available(iOS 11.0, *)) {

    headerCell.insetsLayoutMarginsFromSafeArea = NO;
    headerCell.layoutMargins = UIEdgeInsetsMake(10, 0, 10, 0);
    UIEdgeInsets i = headerCell.layoutMargins;
    NSLog(@"Left: %f", i.left);
}

Sadly this doesn't work.

Here is a mockup of what it should look like, with the first cell contents NOT being affected by the safe area:

Is there any way to do what I am wanting just for the first cell?

Answer 1

I found that I needed to uncheck the Content View Insets To Safe Area checkbox that is on the UITableView.

Doing this fixed the issue!

Answer 2

Marking the "Content insets" under Size Inspector to "Never" worked for me.
