What you want to use is NSString(format:) for the visual format of your value.

To always show 2 digits visually use this:

NSString(format: "%.2f", value)

BIG Thanks, and this extension for that extension Double { func format(f: String) -> String { return NSString(format: "%\(f)f", self) as String } } – Mohammad Al-Shawamreh Nov 12 '15 at 09:57
