RSDStepTextFieldCellLayoutConstants defines the layout constants used by a RSDStepTextFieldCell.

RSDLoadingViewControllerProtocol is a convenience protocol to allow UIViewControllers that do not inherit from the same subclass to show and hide a loading indicator.

RSDPickerViewProtocol is a protocol for an input view that can be used to pick an answer.

RSDPickerObserver is an observer of changes to the picker.

Constants used by the navigation view header to set up standard constraints.

Constants used by the navigation view footer to set up standard constraints.

RSDOptionalStepViewControllerDelegate is a delegate protocol defined as @objc to allow the methods to be optionally implemented. As such, these methods cannot take Swift protocols as their paramenters.

RSDStepViewControllerDelegate is an extension of the RSDUIActionHandler protocol that also implements optional methods defined by RSDOptionalStepViewControllerDelegate.

Protocol to allow setting the step view controller delegate on a view controller that may not inherit directly from UIViewController.

RSDPageViewControllerProtocol allows replacing the UIPageViewController in the base class with a different view controller implementation. It is assumed that the implementation is for a view controller appropriate to the current device.

RSDOptionalTaskViewControllerDelegate is a delegate protocol defined as @objc to allow the methods to be optionally implemented. As such, these methods cannot take Swift protocols as their paramenters.

RSDTaskViewControllerDelegate is an extension of the RSDTaskControllerDelegate protocol that also implements optional methods defined by RSDOptionalTaskViewControllerDelegate.

Optional protocol that can be used to get the step view controller from the step rather than from the task view controller or delegate.

RSDSoundPlayer is a protocol for playing sounds intended to give the user UI feedback during the running of a task.
