Multiple variable assignment in Swift

Question

How do I assign multiple variables in one line using Swift?

    var blah = 0
    var blah2 = 2

    blah = blah2 = 3  // Doesn\'t work???

As the accepted answer says: You can get some tighter syntax, however you cannot assign from a to b to c without using multiple lines (for safety, probably). Here's an example of some more concise syntax to declare and assign multiple variables in one line:

var red, green, blue, alpha : CGFloat
(red, green, blue, alpha) = (0.0, 0.0, 0.0, 0.0)
ledColor.getRed(&red, green: &green, blue: &blue, alpha: &alpha)
