Use sizeof as follows:

let size = sizeof(Int)

sizeof uses the type as the parameter.

If you want the size of the anInt variable you can pass the dynamicType field to sizeof.

Like so:

var anInt: Int = 5
var anIntSize: Int = sizeof(anInt.dynamicType)

Or more simply (pointed out by user102008):

var anInt: Int = 5
var anIntSize: Int = sizeofValue(anInt)
