Random class on iOS, does it exist

Been a while since I have used Xojo - since the RB days. Anyway, working on a simple canvas subclass to set up a simple game app. About thirty minutes in, I’m seeing that the Random class apparently can’t be declared in my project. So I did the same in a desktop app and Random declares fine, and works fine.

1 - Assuming the iOS support just doesn’t include Random, Is there a list of other methods/classes/constructs that currently don’t work with iOS?
2 - Do I have to import a class module or something to get access to standard Xojo classes like Random?
3 - Am I just really missing something?

Thanks everybody
