ios - How to display date read "Today, 14 April"?

Question

I want to present some dates which reads

Yesterday, 13 April
Today, 14 April
Tomorrow, 15 April
Tuesday, 4 April
Wednesday 5 April

I tried

        let date = Date(timeIntervalSince1970: value)

        let dayFormatter = DateFormatter()
        dayFormatter.dateStyle = .medium
        dayFormatter.doesRelativeDateFormatting = true

        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "d MMMM"
        whenLabel.text = dayFormatter.string(from: date) + ", " + dateFormatter.string(from: date)

It is working fine as expected if the date is today, but, for other dates, I get “Apr 5, 2017, 5 April”

How can I get ride of this issue?

You will need two completely different formatters depending on whether the date is today or not. doesRelativeDateFormatting won't help you with complex formatting.

Start by checking:

if Calendar.current.isDateInToday(date) {
   // use "Today, " + "d MMMM" pattern
} else {
   // use "EEEE" pattern + "d MMMM" pattern
}

So for Yesterday, Today and Tomorrow one has to set it static in date formater? – Ashwin Kanjariya Apr 13 '17 at 09:39
@AshwinIndianic Yes because you want to have a formatter which is both relative and not relative. "Today" is usually the replacement for "14 April". That's why you need a custom solution. – Sulthan Apr 13 '17 at 10:06
Okay got your point, Thanks for helping me to improve my knowledge. :) – Ashwin Kanjariya Apr 13 '17 at 10:29

As Sulthan suggest I just come to know about this kind of code,

let mydate = Date()//my actual date need to display
let dateFormatter = DateFormatter()
if Calendar.current.isDateInToday(mydate) {
     dateFormatter.dateFormat = "'Today,' d MMMM"
}
else if Calendar.current.isDateInYesterday(mydate) {
      dateFormatter.dateFormat = "'Yesterday,' d MMMM"
}
else if Calendar.current.isDateInTomorrow(mydate) {
      dateFormatter.dateFormat = "'Tomorrow,' d MMMM"
}
else{
     dateFormatter.dateFormat = "EEEE, d MMMM"
 }

Please update me if we have any better way. Thanks

all static strings should be in quotes! e.g. `'Today,' d MMMM` – Sulthan Apr 13 '17 at 10:07
Okay thanks, (y), I was unaware about ' (single quotes). – Ashwin Kanjariya Apr 13 '17 at 10:27

Just for fun this is a solution which takes advantage of the localized relative date formatting.

It uses an extension of Calendar which determines if a date is in yesterday, today or tomorrow:

extension Calendar {
    func isDateInYesterdayTodayTomorrow(_ date: Date) -> Bool
    {
        return self.isDateInYesterday(date) || self.isDateInToday(date) || self.isDateInTomorrow(date)
    }
}

func relativeDateString(for date: Date, locale : Locale = Locale.current) -> String
{
    let dayFormatter = DateFormatter()
    dayFormatter.locale = locale
    if Calendar.current.isDateInYesterdayTodayTomorrow(date) {
        dayFormatter.dateStyle = .medium
        dayFormatter.doesRelativeDateFormatting = true
    } else {
        dayFormatter.dateFormat = "EEEE"
    }
    let relativeWeekday = dayFormatter.string(from: date)

    let dateFormatter = DateFormatter()
    dateFormatter.locale = locale
    dateFormatter.dateFormat = "d MMMM"
    return  relativeWeekday + ", " + dateFormatter.string(from: date)
}
