Convert string to date in Swift

161

How can I convert this string "2016-04-14T10:44:00+0000" into an NSDate and keep only the year, month, day, hour?

The T in the middle of it really throws off what I am used to when working with dates.

  • Convert the ISO8601 string to date

    let isoDate = "2016-04-14T10:44:00+0000"
    
    let dateFormatter = DateFormatter()
    dateFormatter.locale = Locale(identifier: "en_US_POSIX") // set locale to reliable US_POSIX
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
    let date = dateFormatter.date(from:isoDate)!
    
  • Get the date components for year, month, day and hour from the date

    let calendar = Calendar.current
    let components = calendar.dateComponents([.year, .month, .day, .hour], from: date)
    
  • Finally create a new Date object and strip minutes and seconds

    let finalDate = calendar.date(from:components)
    

Consider also the convenience formatter ISO8601DateFormatter introduced in iOS 10 / macOS 12:

let isoDate = "2016-04-14T10:44:00+0000"

let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from:isoDate)!

Try the following date Format.

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter. dateFromString (strDate)

Hope it helps..

Swift 4.1 :

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"
let date = dateFormatter.date(from: strDate)
