I have a UIView that i create with a XIB. I then want to add it on top of a parent, take up the whole screen but use the safe area i have set up constraints for in the xib.

I can add the view fine, but when i do, the safe area is ignored, and the view goes all the way to the top and bottom.

The code i use (objective-c still sorry):

Code Block (UIView *parent)
MyViewController *newViewController = [[MyViewController alloc] initWithNibName:MY_VIEW_NIB_NAME bundle:nil];
[view setFrame:CGRectMake(0, 0, parent.bounds.size.width, parent.bounds.size.height)];
[parent addSubview:self.view];

In the Xib, i have the top and bottom constrained to SafeArea.top and bottom. It looks fine in the layout there.

Any tips are appreciated.

I'm not sure I fully understand.

Did you set constraint inside the UIView xib relative to safe area ?
How did you do it ?

I would do differently: don't have constraints inside the xib relative to Safe area
Set constraints in code for UIView relative to Safe area by creating constraints programmatically.
