better way to get the name of the day on ios swift

Question

i take the name of the day like this

func loadDayName(forDate date: NSDate) -> String{
    let myComponents = calendar.components(.Weekday, fromDate: date)
    let weekDay = myComponents.weekday
    switch weekDay {
    case 1:
        return "Sunday"
    case 2:
        return "Monday"
    case 3:
        return "Tuesday"
    case 4:
        return "Wednesday"
    case 5:
        return "Thursday"
    case 6:
        return "Friday"
    case 7:
        return "Saturday"
    default:
        return "Nada"
    }
}

it is working find but it i was wondering if swift comes with some libraries to do that automatically better than me do that in code like manually

Solution 1

Use DateFormatter

Swift 4

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE"
let dayInWeek = dateFormatter.string(from: date)

Swift3

let date = NSDate()
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat  = "EEEE" // "EE" to get short style
let dayInWeek = dateFormatter.stringFromDate(date) // "Sunday"    

Screenshot

Solution 2

If you want to get the array of day names you could use: weekdaySymbols in Calendar()

example:

let calendar = Calendar(identifier: .gregorian)
let days = calendar.weekdaySymbols

Solution 3

You can check also this DateFormatter

let dayNameFormatter: DateFormatter = {
    let dateFormatter = DateFormatter()
    dateFormatter.locale = .current
    dateFormatter.calendar = .current
    dateFormatter.dateFormat = "cccc"
    return dateFormatter
}()

print(dayNameFormatter.string(from: Date())) Prints today's day name 🤪

c - stands for day of the week, good answer, official source

You should use NSDateFormatter with a custom date format. developer.apple.com/library/mac/documentation/Cocoa/Referenc‌​e/…

[sarah]

@Darren i already do that but that has nothing to do with the question that is why i didn't show you the code for it

[Darren]

You can configure a date formatter to print just the full day name for a given NSDate.

This is not a duplicate. The other question is more broad. This is the best question for this specific question and answer.

[Leo]

I agree with Joshua that this is not a duplicate question

[sarah]

it is a good option, but the array contains ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"] not full name for days like i want

[Leo]

With shortWeekdaySymbols ,you can get short String.Like the code I update

[sarah]

how did you know that weekdaysSymbols contain the full names? i printed it, both of them contain the short name. +1 for the efforts

[Leo]

The weekdaysSymbols just works well on my playground. You can also use dateFormatter.Like the code I update

[Joshua Dance]

In Swift 4 the stringFromDate is now formatter.string(from: now)

[Teodor Ciuraru]

Yes, but right after you set the calendar.locale.

[Iulian Onofrei]

Make sure you also set the locale for the dateFormatter if you care about i18n.

From nsdateformatter.com There isn't an EE option. EEEEE gets MTWTFSS and EEEEEE gets MoTuWeThFrSaSu
