ysee

that's how it:

let allunits = nscalendarunit(rawvalue: uint.max) return uicalendar.currentcalendar().components(allunits, fromdate: nsdate()) 

note in swift 2.0 bitwise or operator | not used more, instead nscalendarunit conforms optionsettype format:

let timeunits : nscalendarunit = [.hour, .minute, .second]
