This example shows a variety of Date.FormatStyle.Symbol.Week format styles applied to a date:
let meetingDate = Date() // May 3, 2021 at 3:00 PM
meetingDate.formatted(Date.FormatStyle().week(.defaultDigits)) // 19
meetingDate.formatted(Date.FormatStyle().week(.twoDigits)) // 19
meetingDate.formatted(Date.FormatStyle().week(.weekOfMonth)) // 2
meetingDate.formatted(Date.FormatStyle().week()) // 19
An incomplete week at the start of a month is the first week of the month 1. If you don’t provide a format, the defaultDigits static variable is the default format.
