dateFromString() returning wrong date swift 3.0

Question

i am passing "01/12/2017" in the fromDate.text(textfield), but receiving unexpected output.

      let formatter = DateFormatter.init()
      formatter.dateFormat = "dd/mm/yyyy"
      startDate = formatter.date(from: fromDate.text!)
      print("startDate = \(startDate)")

output is : 31/12/2016

Answer 1

The format of date should be dd/MM/yyyy not dd/mm/yyyy. The mm indicates the minutes and MM indicates the month.

And also add the below line in your code

formatter.timeZone = TimeZone(abbreviation: "GMT+0:00")

This line of code set time zone. If you not, then you get 30/11/2017 in output.

The reason behind this is when string date not contain time then formatter assume that it is midnight and you also not given the timezone so it will take current timezone.

Answer 2

It has to be dd/MM/yyyy dateformat. MM in capital.
