Automated convert string into date

Question

How can I automated convert string to date with this code

let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "HH:mm"

    guard let date = dateFormatter.date(from: String) else { return }

so I don't have to type again or reuse again, I was thinking with DateFormatter extension but I don't know how or is that the correct method. Thank you for your attention

Answer 1

You need to create extension on String instead of Dateformatter.

Try with below code,

extension String {

    var date: Date? {
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "HH:mm"
        return dateFormatter.date(from: self)
    }

}

Uses example:

override func viewDidLoad() {
        let dateString = "11:32"
        if let date = dateString.date { //This will return Date object
            debugPrint(date)
        }

        let invalidDateString = "XYZ:ABC"
        if let invalidDate = invalidDateString.date { //This will return nil as date string is invalid
            debugPrint(invalidDate)
        }
    }
