Swift 4 Weak References
Thx Swift Team for the HUGE improvements on weak references in Swift 4 🙌
"Swift's new implementation of weak references brings with it the concept of side tables.
The side table allows Swift to maintain the basic form of the old weak reference system while fixing its flaws. Instead of pointing to the object, as it used to work, weak references now point directly at the side table.
Because the side table is known to be small, there's no issue of wasting a lot of memory for weak references to large objects, so that problem goes away. This also points to a simple solution for the thread safety problem: don't preemptively zero out weak references. Since the side table is known to be small, weak references to it can be left alone until those references themselves are overwritten or destroyed."
