After coding in swift for ~5 years at job - 1, I can count on one hand the times I had to deal with a reference cycle, and in each instance it was obvious in context that there was going to be a cycle so I used “weak” in anticipation. Zero times did I ever accidentally forget to use a weak reference. A simple rule of thumb is that if anything has a parent/child relationship, the child should use the weak keyword (or even “unowned” if you’re certain about object lifetimes) when referring back to the parent. That and things like hand-rolled doubly linked lists, but the standard library already has that so who cares.
