Check the date format of string if it's according to required format or not

Question

I have the same question asked here in Java, is it possible in swift?

func stringToDate(str: String) -> Date{

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "dd/MM/yyyy"

    //check validation of str 

    return date
}

Answer 1

Just same like Java, check if it can parse properly

let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd hh:mm:ss"
let someDate = "string date"

if dateFormatterGet.date(from: someDate) != nil {
    // valid format
} else {
    // invalid format
}
