I’ve been running iOS 12 since the early betas and only rebooted for OS updates. Sure it’s not an app or something?

There's one particular mobile game that is suspicious... However, this issue was nonexistent with iOS 11. The memory diagnostic app shows the "Other" section constantly growing and not being released.

If an app (even badly coded) causes memory leaks in the OS, that's a fault of the OS still. Of course fast moving OSes like Android or iOS are always going to have these kinds of bugs and it's probably not related to Swift as Swift isn't used in the kernel internals.

    Well, leaking kernel memory is very different than leaking application memory, because one can be paged out while the other is wired permanently.

      Wired? All memory is always physically wired to the motherboard. It's unsafe for the kernel to swap the memory out, because paging doesn't (usually) work while running kernel code.

        Wired as in not swappable.

        I write kernel mode drivers as my day job, and this is certainly the first time I've ever heard of non-swappable being called "wired". It might be called "non-pageable", "pinned", "non-swappable", etc. Out of those, I'd prefer "non-pageable", because it's the most descriptive term for it. Non-standard terminology is not great for communication.

Because it's literally called that in macOS Activity Monitor app, the term is also used in Apple's kernel documentation and API's (e.g. in the `mem_and_io_snapshot` struct defined in 'debug.h' in Kernel.framework). It's also mentioned in the Kernel Programming Guide.

        Interesting. Never did macOS drivers, just bare metal, Windows and Linux so far, macOS is not very big in our niche. Weird that Apple's terminology is so different. Typing this on a Macbook Pro, and I can see that Activity Monitor does mention "wired" memory.
