Hi hope someone can help me. I need to calculate the days between to dates. The flow are:

Pick a date
New date by years (ex. 2 years)
Get the days between the "pick date" and the "New date"

Another tip for future questions is to show how you've gone about trying to solve this. — hannad, Feb 18 '16 at 08:24

Try this code, updated for Swift 2.0

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

let first = "2010-09-01"
let firstDate = dateFormatter.dateFromString(first)!
let last = "2010-09-05"
let lastDate = dateFormatter.dateFromString(last)!

let currentCalendar = NSCalendar.currentCalendar()
let timeUnitDay = NSCalendarUnit.Day

let daysBetween = currentCalendar.components(timeUnitDay, fromDate: firstDate, toDate: lastDate, options: NSCalendarOptions.MatchStrictly)

print(daysBetween.day)
