弱引用的代表变为零

Question

I'm creating a delegate with weak reference and need to go through the couple of completions(closures) then delegate becomes nil. When I remove the weak reference it works fine.

weak var contentDelegate: ContentDelegate?

Actually is it allow to create a delegate property without weak reference in swift best practices? What are the drawbacks?

Yes you can create delegates without weak reference .

No it's not under best practices scope .

Drawbacks, are mainly the risk of having a retain cycle where references are not getting released from memory, leading to a memory leak .

Answer 2

would be great if you can share your code. Without code hard to say, but looks like you have async calls, and on some async call delegate , I suppose it's controller or maybe some service, released from the memory

if you remove weak you will get retain cycle, when delegate and owner of this delegating are holding each other in the memory
