A class may indicate that it does not support weak references by providing the
``objc_arc_weak_unavailable`` attribute on the class's interface declaration. A
``objc_arc_weak_reference_unavailable`` attribute on the class's interface declaration. A
retainable object pointer type is **weak-unavailable** if
is a pointer to an (optionally protocol-qualified) Objective-C class ``T`` where
``T`` or one of its superclasses has the ``objc_arc_weak_unavailable``
``T`` or one of its superclasses has the ``objc_arc_weak_reference_unavailable``
attribute. A program is ill-formed if it applies the ``__weak`` ownership
qualifier to a weak-unavailable type or if the value operand of a weak
assignment operation has a weak-unavailable type.
