I either don't understand or can't reproduce the issue. This code:
> class Box {
> let value: Int
>
> init(value: Int) {
> self.value = value
> }
> }
>
> let test: UInt32 = 4
> let box = Box(value: test)
does not compile ("foo.swift:10:22: error: cannot convert value of type
'UInt32' to expected argument type 'Int'").
