This sounds like an excellent idea. Now my bottom UIToolbar looks like: Flexible Space, ViewWithSlider, Flexible Space ViewWithSlider is: import UIKit class ViewWithSlider: UIView { init( coder: NSCoder ) { let functionName = "-[ViewWithSlider initWithCoder] " println(functionName + "will call super") super.init(coder: coder) } override func updateConstraints() { let functionName = "-[ViewWithSlider updateConstraints] " println(functionName + "will call super") super.updateConstraints() } override func sizeThatFits( size: CGSize ) -> CGSize // never called { let functionName = "-[ViewWithSlider sizeThatFits \(size)] " let superSize = super.sizeThatFits( size ) println(functionName + "super fits \(superSize)") return superSize } override func systemLayoutSizeFittingSize( size: CGSize ) -> CGSize // never called { let functionName = "-[ViewWithSlider systemLayoutSizeFittingSize \(size)] " let superSize = super.systemLayoutSizeFittingSize( size ) println(functionName + "super fits \(superSize)") return superSize } } and it prints: -[ViewWithSlider initWithCoder] will call super -[ViewWithSlider updateConstraints] will call super But nobody ever cares to call sizeThatFits or systemLayoutSizeFittingSize. Overriding requiresConstraintBasedLayout and returning either YES or NO makes no difference. Anything else I forgot to override?
