I wish to be able to generate a random number from within a part

Answer 1

In order to avoid the modulo bias (suggested in other answers) you can always use:

arc4random_uniform(MAX-MIN)+MIN

Where "MAX" is the upper bound and "MIN" is lower bound. For example, for numbers between 10 and 20:

arc4random_uniform(20-10)+10

arc4random_uniform(10)+10

Simple solution and better than using "rand() % N".
