QUESTION 5 OF 28

A huge part of our business here at Snapchat is designing software for iOS. In this role, how would you steer away from retain cycles when using closures in Swift programming language?

This question allows your interviewer to assess your technical knowledge and skills in designing apps for iOS products in a very simple way. To successfully answer it, make sure that you can speak knowledgeably about the swift programming language and using closures to capture and store references within the software. To piece together everything for your interviewer, give a clear understanding of why retain cycles must be avoided in your processing.

"Because ARC handles most of the memory knowledge in Swift, I know ARC is prone to memory leaking and this can cause major issues in apps over time. The fix that I've used in my career to avoid retain cycles is using weak references in my coding."
