You can find out constraint like that

extension UIView {
    var heightConstaint: NSLayoutConstraint? {
        get {
            for constraint: NSLayoutConstraint in constraints {
                if constraint.firstAttribute == .height {
                    if constraint.relation == .equal {
                        return constraint
                    }
                }
            }
            return nil
        }

        set{
            setNeedsLayout()
        }
    }
}
