Thanks for submission!

I've had some feedback that I've made a bit of a mess with casting when trying to calculate a random number - would appreciate any best practices or thoughts on that...

you're right, in my example arc4random_uniform works perfectly and unlike rand() you don't have to seed.

delay = NSTimeInterval(arc4random_uniform(900)+100) / 1000

Not sure why I didn't do that in the first place...
