Help about Arc4random

This won't work, and i can't figure out why.

var randomNum = arc4random()

if randomNum == 1 { ...} else if randomNum == 2 { ...} and so on...

It says "Cannot invoke 'arc4random' with an argument list of type (Int)"

The function arc4random() returns a UInt32 object not a Int one. That's why you get the message: "Cannot invoke 'arc4random' with an argument list of type (Int)"

You can transform your Int object in UInt32 with these: var x = UInt32(yourInt)
