How to get .date style in uppercase?

Question

If I've got this text block

 Text("Logged On: \(theDate, style: .date))")

Is there anything I can do to get the date text converted to all caps? Just adding a

.textCase(.uppercase)

isn't working.

Answer 1

Rather than using the style: parameter, which takes aText.DateStyle, use the format: parameter, which takes a FormatStyle. The latter is much more customisable.

You can make your own FormatStyle, and pass it to format:

struct CapitalisedFormatStyle: FormatStyle {
    func format(_ value: Date) -> String {
        // delegate to the built-in date format style
        Date.FormatStyle(date: .long).format(value)
            .localizedUppercase
            // or just .uppercased() if you prefer
    }
}

// for easy access with just .capitalisedDate
extension FormatStyle where Self == CapitalisedFormatStyle {
    static var capitalisedDate: CapitalisedFormatStyle { .init() }
}

Text("Logged On: \(someDate, format: .capitalisedDate)")
