How to make the st,nd,rd,th as superscript along with date and time in swift ios – Ios swift

How to make the st,nd,rd,th as supescript along with date and time in swift xcode 13.
I have set the items in the tableviewcell

From the tableView cell I’m setting the date and time like in below code

let date = meetingListArray[indexPath.row].callScheduleDate?.dateConversion(date: meetingListArray[indexPath.row].callScheduleDate ?? "") ?? ""
        let toTime = meetingListArray[indexPath.row].timeTo?.timeConverter(date: meetingListArray[indexPath.row].timeTo ?? "") ?? ""
        let fromTime = meetingListArray[indexPath.row].timeFrom?.timeConverter(date: meetingListArray[indexPath.row].timeFrom ?? "") ?? ""
        let time = fromTime + " -" + toTime
        cell.callDateAndTime.text = date  + time

I have written the the dateFormatWithSuffix(), daySuffix() as extension

 func dateFormatWithSuffix() -> String {
            return "MMMM dd'(self.daySuffix())' yyyy  | "
        }

        func daySuffix() -> String {
            let calendar = Calendar.current
            let components = (calendar as NSCalendar).components(.day, from: self)
            let dayOfMonth = components.day
            switch dayOfMonth {
            case 1, 21, 31:
                return "st"
            case 2, 22:
                return "nd"
            case 3, 23:
                return "rd"
            default:
                return "th"
            }
        }

I have added the image of date and time here

    You can Use the same code of @DonMag There is a small Correction.

    cell.callDateAndTime.text = firstPart
//instead of this line  use
cell.callDateAndTime.attributedText = firstPart

    Because we can't assign a NSAttributedString to a label.There will be an error if you use .text. "Cannot assign value of type 'NSMutableAttributedString' to type 'String?'".

    One way to do this is with an Attributed string.

    For example (using your daySuffix() func):

        let someDate: Date = Date()

    let df = DateFormatter()

    // use DateFormatter and/or Calendar Components to get
    //  Month Name, dayOfMonth, year (as Strings)
    df.dateFormat = "MMMM"
    let m: String = df.string(from: someDate)
    
    df.dateFormat = "d"
    let d: String = df.string(from: someDate)

    df.dateFormat = "yyyy"
    let y: String = df.string(from: someDate)
    
    // get the day suffix
    let dsf = someDate.daySuffix()
    
    // however you parse/format your to/from times
    let theTimePart: String = "12:00 AM - 12:00 AM"
    
    // font for everything except the superscript
    let font1: UIFont = .systemFont(ofSize: 12.0, weight: .regular)
    // font for the superscript (slightly smaller)
    let font2: UIFont = .systemFont(ofSize: 8.0, weight: .regular)
    
    // atributes for "main" part of string
    let mainAttributes: [NSAttributedString.Key: Any] = [.font: font1]
    
    // atributes for "superscript" part of string
    //  baselineOffset of the difference between the two font sizes
    //  seems to work fairly well
    let superscriptAttributes: [NSAttributedString.Key: Any] = [.font: font2, .baselineOffset: (font1.pointSize - font2.pointSize)]

    // first part will be (for example) "August 17" with main attributes
    let firstPart = NSMutableAttributedString(string: m + " (d)", attributes: mainAttributes)
    // second part will be the day suffix (st,nd,th,rd) with superscript attributes
    let secondPart = NSAttributedString(string: dsf, attributes: superscriptAttributes)
    // third part will be (for example) " 2022 | 12:00 AM - 12:00 AM" with main attributes
    let thirdPart = NSAttributedString(string: " (y) | (theTimePart)", attributes: mainAttributes)
    
    // append second part
    firstPart.append(secondPart)
    // append third part
    firstPart.append(thirdPart)
    
    // set the label's attributed text
    cell.callDateAndTime.text = firstPart
