Generating random number 1 - 100 in Swift 2 [duplicate]

Question

I was wondering if this is the best way to generate a random number in Swift.

This is what I have thought of thus far:

var randomNumber:Int = random() * 100 + 1 //What value does this return?

I was wondering if this is a viable 1 - 100 range in Swift utilizing the random() function? I am unsure if this is. I have not dealt with random numbers much in Swift 2. However in Java, the equivalent would be Math.random() * 100 + 1

I'm curious to know what would be the equivalent of this in Swift 2. Thanks in advance!

@originaluser2 I think it doesn't when it detects a comment with the link already in it, and there was one at this moment. — Eric Aya

-1

let random = Int(arc4random_uniform(100) + 1)

+ 1 since arc4random_uniform generates a random number between 0 and the parameter - 1

really? do we need 2 virtually identical answers on a question that's a duplicate anyway?

Are you sure this still works in the latest iteration of XCode and Swift? I do not see this option anymore in Xcode.

@Linuxn00b you have to import the Darwin module (as stated in the duplicate question)

@originaluser2 it seems to work without the Darwin module. Thanks for all your help.
