Remarks

Auto Layout uses the Constraints of a UIView to lay out its Subviews. These constraints are set with AddConstraint(NSLayoutConstraint) or AddConstraints(NSLayoutConstraint[]).

The P:UIKit.NSLayoutConstraint.DebugDescription property can be helpful in debugging Auto Layout issues.

foreach(var c in mainView.Constraints)
{
    Console.WriteLine(c.DebugDescription);
}
