simple swift random class

Random.swift

import UIKit


class Random {
	
	class func randomInt() -> Int {
		return Int(arc4random());
	}
	
	class func randomIntFrom(from: Int) -> Int {
		return from + Int(arc4random())
	}
	
	class func randomIntTo(to: Int) -> Int {
		return Int(arc4random()) % (to + 1)
	}
	
	class func randomInt(from: Int, to: Int) -> Int {
		return from + Int(arc4random()) % (to - from)
	}
	
	class func randomInt(range: Range<Int>) -> Int {
		return self.randomInt(range.startIndex, to: range.endIndex)
	}
	
	class func randomDouble(from: Double, to: Double) -> Double {
		return drand48()
	}
	
}

nice range function

thx 👍
