> It’s possible to do this correctly if you actually read the docs and understand what you’re doing, using tools like weak pointers, but when you have hundreds of developers, many of whom got their job either by transferring from an android team or by just memorizing pat answers to all the “Ninja” algorithms interview questions (practically all of which have leaked on Leetcode and various forums), you can be sure that enough of them will fail to do so to create major issues with OOMs. This pretty much nails down what I imagine is the main difference between GC and ARC: with the former you sacrifice performance for ease of use, and with the latter you improve performance by placing some additional work on the programmers.
