RVS_WeakObjectReference

public struct RVS_WeakObjectReference<T> : Equatable, Hashable where T : AnyObject

This allows us to maintain collections of weak references.

USAGE:

Create instances of RVS_WeakObjectReference, with the values being the objects that you want to aggregate weakly. Aggregate these instances.

Each instance keeps a hash of the original object, even if that object is released, so we can use these as hashable keys or set members.

Note

Remember to access the value property of each instance, instead of the instance, itself. The value will always be an optional, and may be nil.
