transforming a weekday integer to a string - swift

Question

I currently have an array of weekdays that represent integers which I will trigger a notification on that weekday

let weekdays:[Int] = [1,4,7]

• in dateComponents, weekdays represent a number so for example - integer 1 represents Sunday and integer 7 represent Saturday - I was wondering how can I transfer those integers to a weekday string - for example in the array weekdays I have [1,4,7] - I want to then print out [Sunday, Wednesday, Saturday] is there a way to do that? any help would be great.

Answer 1

Assuming you are ok with 1 = Sunday and 7 = Saturday, maybe something like this can be done:

First sort the array

weekdays = weekdays.sorted()

Then iterate through it

for i in weekdays {
    let weekdayString = Calendar.current.weekdaySymbols[i - 1]
    print(weekdayString)
}

Depending on your needs you may wish to use:

.weekdaySymbols
.shortWeekdaySymbols
.veryShortWeekdaySymbols

or

.standaloneWeekdaySymbols
.shortStandaloneWeekdaySymbols
.veryShortStandaloneWeekdaySymbols
