How to get start and end time of current date?

Answer 1

You can use startOfDayForDate to get today's midnight date and then get end time from that date.

//For Start Date
let calendar = NSCalendar.currentCalendar()
calendar.timeZone = NSTimeZone(abbreviation: "UTC")! //OR NSTimeZone.localTimeZone()
let dateAtMidnight = calendar.startOfDayForDate(NSDate())

//For End Date
let components = NSDateComponents()
components.day = 1
components.second = -1
let dateAtEnd = calendar.dateByAddingComponents(components, toDate: startOfDay, options: NSCalendarOptions())
print(dateAtMidnight)
print(dateAtEnd)

Edit: Convert date to string

let dateFormatter = NSDateFormatter()
dateFormatter.timeZone = NSTimeZone (abbreviation: "UTC")! // OR NSTimeZone.localTimeZone()
dateFormatter.dateFormat = "dd-MM-yyyy HH:mm:ss"
let startDateStr = dateFormatter.stringFromDate(dateAtMidnight)
let endDateStr = dateFormatter.stringFromDate(dateAtEnd)
print(startDateStr)
print(endDateStr)
