DateTransformer.stringToString(string: "2022-01-25", 
                               inputCharacteristcs: DateCharacteristcs(
                               format: DateFormats.YYYY_MM_DD.rawValue), 
                               outputCharacteristcs: DateCharacteristcs(

Comparing dates

let date1 = Date() // ex: "25-01-2022"
let date2 = Calendar.current.date(byAdding: .month, value: 1, to: date1) // ex: "25-02-2022"

//check if date is before another date
if DateTransformer.isBefore(firstDate: date1, secondDate: date2) {
    //Do some thing
}

//check if date is before or equal another date
if DateTransformer.isBefore(firstDate: date1, secondDate: date2, orEqual: true) {
    //Do some thing
}

//check if string of date is before another string of date
if DateTransformer.isBefore(firstDate: "01-01-2014",
                            firstDateCharacteristcs: DateCharacteristcs(
                            format: DateFormats.DD_MM_YYYY.rawValue), 
                            secondDate: "01-01-2028", 
                            secondDateCharacteristcs: DateCharacteristcs(
                            format: DateFormats.DD_MM_YYYY.rawValue)) {
    //Do some thing
}

also,

//check if date is After another date
if DateTransformer.isAfter(firstDate: date2, secondDate: date1) {
    //Do some thing
}
