Is there some process to convert a negative -4000 'Int' into a 'UInt8'?

As much as it would be nice to think of things in this way, "%x" is just too archaic and I wouldn't touch it.

How to use the new FormatStyle to format an Int to hex?

Just a quick note about the big picture here: The new number formatting facilities are conceptually a wrapper around the existing NumberFormatter class. NumberFormatter is focused on localised strings, which is why NumberFormatter.Style has no .hexadecimal value. In contrast, String.init(_:radix::uppercase:) produces a non-localised string. To my mind trying to mix these two seems like a type error. Share and Enjoy Quinn “The Eskimo!” @ DTS @ Apple
