Simple to use swift functions which are very useful in development and testing.
1. Generating random UIColor in Swift: Function returns random UIColor each time
func randomUIColor(alpha:CGFloat!)-> UIColor { return UIColor(red: CGFloat.random(in: 0...1), green: CGFloat.random(in: 0...1), blue: CGFloat.random(in: 0...1), alpha: alpha) }
2. Random HEX Color code in Swift 3: Function returns random 3 char Hex colour code each time.
