I am new to programming and recently started learning Swift language. To test my learning i am trying to make an app like "Alarm Clock". Initially i thought that i can assign datepicker.date to notification date but soon i realize that datepicker is not giving the exact value. I had no idea how to do it but after a good amount of research on this website i got some understanding about how to implement. I started making the app but now i stuck with a problem. I created a date picker to set the alarm and i used NSDateFormeter function to extract the string from the date. and i made an array with that string and used dateFromComponents to make a date. When i try to print them, the array giving correct numbers but after making date with it the date is coming out different. Please help me to solve this. Thank you very much for help.

@IBAction func mydatepickerAction(sender: AnyObject) {
var daFormet = NSDateFormatter()
//For ex: 2015:01:17:20:05
daFormet.dateFormat = "YYY:MM:dd:HH:mm"
//This makes datestring from Datepickersdate
var dateString:String = daFormet.stringFromDate(mydatePicker.date)
//Makes an array from the date String
myArray = dateString.componentsSeparatedByString(":")
}
@IBAction func myButton(sender: AnyObject) {
println(myArray)
//Creates a date from components
var newMyDate:NSDate = dateFromComponents(myArray[2] .toInt()!, month: myArray[1] .toInt()!, year: myArray[0] .toInt()!, hour: myArray[3] .toInt()!, minute: myArray[0] .toInt()!, second: 00)
println(newMyDate)
var date = NSDate()
println(date)
}
func dateFromComponents(day:Int, month:Int, year:Int, hour:Int, minute:Int, second:Int) -> NSDate {
var cal = NSCalendar(calendarIdentifier: NSGregorianCalendar)!
cal.timeZone = NSTimeZone.localTimeZone()
var comps = NSDateComponents()
comps.day = day
comps.year = year
comps.second = second
comps.hour = hour
comps.minute = minute
comps.month = month
return cal.dateFromComponents(comps)!
}
