Convert Float to Int in Swift

I want to convert a Float to an Int in Swift. Basic casting like this does not work because these types are not primitives, unlike floats and ints in Objective-C

var float: Float = 2.2
var integer: Int = float as Float

But this produces the following error message:

‘Float’ is not convertible to ‘Int’

Any idea how to property convert from Float to Int?
