passUnretained(_:)
Creates an unmanaged reference without performing an unbalanced retain.
static func passUnretained(_ value: Instance) -> Unmanaged<Instance> Parameters

An unmanaged reference to the object passed as value.
This is useful when passing a reference to an API which Swift does not know the ownership rules for, but you know that the API expects you to pass the object at +0.
