A more relevant bit of background is that 4KB pages lead to quite a lot of overhead due to the sheer number of mappings needing to be configured and cached. Using larger pages reduce overhead, in particular TLB misses as fewer entries are needed to describe the same memory range.
While x86 chips mainly supports 4K, 2M and 1G pages, ARM chips tend to support more practical 16K page sizes - a nice balance between performance and wasting memory due to lower allocation granularity.

Nothing in particular to do with Apple and iOS.
