    If u want to convert any Date object to this format do this.

    let date = Date()

//create the date format without the day
let dateFormatter = DateFormatter()
dateFormatter.locale     = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "MMMM,yyyy HH:mm"
let dateWithoutDay = dateFormatter.string(from: date)

//get the day from the date
let dayFormatter = DateFormatter()
dayFormatter.locale     = Locale(identifier: "en_US_POSIX")
dayFormatter.dateFormat = "d"
let day = dayFormatter.string(from: date)

//create a number formatter to get st/nd/rd/th suffix
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = .ordinal
let dayWithSuffix = numberFormatter.string(from: NSNumber(value:Int(day)!))

    print("(dayWithSuffix!) (dateWithoutDay)") // --> 3rd September,2022 22:52

    If u want to convert this type of date (1st July,2021 17:00 ) to a Date object do this.

    let dateString = "1st July,2021 17:00"
let dateSuffix = dateString.components(separatedBy: CharacterSet.decimalDigits).joined().prefix(2)
let dateFormatter = DateFormatter()
dateFormatter.locale     = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "dd'(dateSuffix)' MMMM,yyyy HH:mm"
let date = dateFormatter.date(from: "1st July,2021 17:00")
print(date!) // ->> 2021-07-01 11:30:00 +0000

    If you want to use localisation support, try this template(playground):

    import Foundation

//let locale = Locale(identifier: "ar")
//let locale = Locale(identifier: "en-us")
let locale = Locale(identifier: "ja")

let dayOfMonth: NSNumber = 11
let dayPlaceholder = "dd"
let dateFormat = DateFormatter.dateFormat(
    fromTemplate: "(dayPlaceholder)MMMM",
    options: 0,
    locale: locale
)

let numberFormatter = NumberFormatter()
numberFormatter.locale = locale
numberFormatter.numberStyle = .ordinal
let dayOrdinalString = numberFormatter.string(from: dayOfMonth)

let ordinalDateFormat = dateFormat?.replacingOccurrences(
    of: dayPlaceholder,
    with: "'(dayOrdinalString ?? "")'"
)

let formatter = DateFormatter()
formatter.locale = locale
formatter.dateFormat = ordinalDateFormat
formatter.string(from: Date())
