I am attempting to take a string in the format dd/mm/yyyy and convert it to an NSDate so I can store a birthday. The day, month, and year are validated to be a real date (not in the future either) so I know that they are correct. They are entered as text fields by the user and I suppose I could make the dateString any format I want it that would be helpful.
let day = dayTextField.text
let month = monthTextField.text
let year = yearTextField.text
let dateString = "\(day)/\(month)/\(year)"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
let birthdate: NSDate = dateFormatter.date(from: dateString) as NSDate
My problem is with the last line when I attempt to cast my date string to an NSDate, I get the following error:
'Date?' is not convertible to 'NSDate'; did you mean to use 'as!' to force downcast?
I could force cast after "(from: dateString)" but I didn't think that would be the right thing to do.
Any help and insight you can provide would be greatly appreciated! Thank you
It is way easier for both you and the user if you let the user choose a date from a UIDatePicker. This has a lot of advantages:
date property. You don't need all these formatters and stuffmaximumDate property. This way you don't have to check if it is in the future manually. Just set maximumDate to now.Just remember to set the datePickerMode to .date!
As for the conversion to NSDate, you can do this easily by this expression:
datePicker.date as NSDate
If you insist on using three text fields, you can do this:
dateFormatter.date(from: dateString) as NSDate? // note that this produces an optional
