I have a UIImageView that I want to add a shadow behind. I wish that apple had that as a property but they have to make lots of things hard for us programmers so I need to ask this question.

The simplest thing to do is add a shadow layer to your image view:
CALayer *layer = [CALayer layer];
CGRect bounds = self.bounds;
layer.bounds = bounds;
layer.position = CGPointMake(bounds.size.width / 2 + 3, bounds.size.height / 2 + 3);
layer.backgroundColor = [UIColor colorWithWhite: 0.25 alpha: 0.55].CGColor;
layer.zPosition = -5;
[self.layer addSublayer: layer];
Be sure "Clip Subviews" is turned off for the view
Swift 5.x
profileImageView.layer.cornerRadius = profileImageView.frame.size.width/2
profileImageView.clipsToBounds = false
profileImageView.layer.shadowColor = UIColor.black.cgColor
profileImageView.layer.shadowOpacity = 0.7
profileImageView.layer.shadowOffset = CGSize(width: 2, height: 2)
profileImageView.layer.shadowRadius = 10
