Something I never see in Swift tutorials, but I would need almost immediately for what I want to do, is low-level disk file writing, e.g. writing bytes, ints, strings, etc. to a file on disk. I guess it doesn’t come up much in app development :) The most I’ve been able to glean so far is it might have something to do with the Data class???
If anyone can point me to resources/APIs I should look at, I’d greatly appreciate it
