The instance of the UIKit.UIScrollViewDelegate model class
This value can be null.
The delegate instance assigned to this object will be used to handle events or provide data on demand to this class.
When setting the Delegate or WeakDelegate values events will be delivered to the specified instance instead of being delivered to the C#-style events
This is the strongly typed version of the object, use the WeakDelegate property instead if you want to merely assign a class derived from NSObject that has been decorated with [Export] attributes.
