Swift Dates Leading Zero

import Foundation

let date = Date()
let dayFormatter = DateFormatter()
dayFormatter.timeZone = TimeZone.current
dayFormatter.locale = Locale.current
dayFormatter.dateFormat = "d"

let monthYearFormatter = DateFormatter()
monthYearFormatter.timeZone = TimeZone.current
monthYearFormatter.locale = Locale.current
monthYearFormatter.dateFormat = "MMMM' in the year of 'yyyy"

let dayString = dayFormatter.string(from: date)
let monthYearString = monthYearFormatter.string(from: date)

let formattedDate = "\(dayString) in the month of \(monthYearString)"

print(formattedDate)

This Swift code is used to format the current date into a specific string format.

Current Date

let date = Date()
  • The Date() function is used to get the current date and time.

Formatters

let dayFormatter = DateFormatter()
dayFormatter.timeZone = TimeZone.current
dayFormatter.locale = Locale.current
dayFormatter.dateFormat = "d"

let monthYearFormatter = DateFormatter()
monthYearFormatter.timeZone = TimeZone.current
monthYearFormatter.locale = Locale.current
monthYearFormatter.dateFormat = "MMMM' in the year of 'yyyy"

  • The DateFormatter() function is used to create formatters for different date and time formats.

  • The timeZone, locale, and dateFormat properties are set for both formatters.

  • Another DateFormatter instance is created for formatting the month and year.

  • timeZone = TimeZone.current and locale = Locale.current are set similarly to ensure consistency.

  • The dateFormat = “MMMM’ in the year of ‘yyyy” specifies the format: MMMM represents the full month name (e.g., “January”, “February”). ’ in the year of ’ is a literal string that will appear in the formatted output. yyyy represents the four-digit year (e.g., “2024”).

String Formatting

let dayString = dayFormatter.string(from: date)
let monthYearString = monthYearFormatter.string(from: date)

let formattedDate = "\(dayString) in the month of \(monthYearString)"
  • The string(from:) method is used to format the date using the formatters.
  • The formatted date is then concatenated to create the final string.

Output

print(formattedDate)
  • The formatted date is printed to the console using the print() function.

Example Output

If the current date is December 18, 2024, the output will be:

18 in the month of December in the year of 2024

Fabulous.

Conclusion

This code demonstrates how to use DateFormatter to format the current date into a custom string format. It separates the day of the month and the month/year into two different formats and then combines them into a single, readable string. This approach allows for flexible and localized date formatting, which can be particularly useful for applications that need to display dates in a user-friendly manner.
