/ has been in use since the inception of unix in 1970 that's 39 years. I seriously doubt it's going to change anytime soon. In 39 more years, i'll be dead.

If you are working with file paths, you shouldn't be using
componentsSeparatedByString:, nor should you be defining "/" to be the
component you should be separating by. What if someone had your app inside
of a folder they named "Apps/Utilities"? The HFS+ filesystem actually uses a
colon as the path separator, so having a / in the name of a file or folder
is perfectly acceptable, but would likely cause a headache and unexpected
results if your code were to encounter it. (Go to the Finder and try adding
a /).
What you're saying here is incredibly misleading, and actively harmful.
While I believe that HFS+ uses ":" as a path separator on-disk, virtually
all non-Carbon userspace code makes use of UNIX paths. Either Carbon or the
Finder itself is swapping colons and slashes for display purposes - running
"ls" should reveal that filenames which appear as slashes in the Finder
appear as colons.
It is a baffling myth, and I can't understand how anyone with any
experience with the system would actually believe it. The OS goes
through a great deal of trouble to make HFS+ filesystems look and
behave exactly like any other UNIX-visible filesystem. Do you not use
Terminal? Do you not examine any of the hundreds or thousands of paths
flying through your application? They *all* use / as the path
separator.
(The reason a folder named Apps/Utilities does not break things is
because at the UNIX level this is represented as Apps:Utilities. / is
not allowed in filenames at that level, period. Doesn't matter what
filesystem you're on.)
