How to add minutes to current time in swift

how to add 30 minutes to current time

Here is my code:

 endFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
 let endTimeString = "2017-01-16 12:58:56"
 let endTime = endFormatter.dateFromString(endTimeString)
 endTime?.dateByAddingTimeInterval(180) // 3 Minute
 print(endTime)

1st answer @rob i tried that one but failed . second answer suggest dateByAddingTimeInterval i am not suer is it is work or not .

Answer 1

You need to use dateByAddingUnit as @Rob doing instead of dateByAddingTimeInterval . The reason you are not getting correct time is may because of TimeZone so try to set timeZone with your NSDateFormatter instance.

endFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
endFormatter.timeZone = NSTimeZone(abbreviation: "UTC")
let endTimeString = "2017-01-16 12:58:56"
let endTime = endFormatter.dateFromString(endTimeString)

//Now add the 3 minute in endTime

let calendar = NSCalendar.currentCalendar()
let date = calendar.dateByAddingUnit(.Minute, value: 3, toDate: endTime, options: [])

Answer 2

let dateWithMinuteInterval = Calendar.current.date(byAdding: DateComponents(minute: 23), to: endTime)!
