## Discussion

Discussion This method attempts to parse a provided string into an instance of date using the source date format style. The function throws an error if it can’t parse the input string into a date instance. The date format style guides parsing the date instance from an input string, as the following example illustrates. let birthdayFormatStyle = Date.ISO8601FormatStyle()         .dateSeparator(.dash)     .timeSeparator(.colon)     .year()     .month()     .day()     .time(includingFractionalSeconds: false)

// Create a date instance from a string representation of a date. let yourBirthdayString = "2021-02-17T14:33:25" let yourBirthday = try? birthdayFormatStyle.parse(yourBirthdayString) // Feb 17, 2021 at 8:33 AM
