custom-repeat-date

A simple date extension that easily allows you to provide custom repeat date options for the Gregorian calendar. The package has been created and used for Expenses.app, inspired by Apple Reminders and Bluebird.

Usage

let option = CustomRepeatDateOption.monthly(frequency: 3, option: .daysOfWeek(weekdayOrdinal: .second, weekday: .tuesday))
let calendar = Calendar(identifier: .gregorian)

let startDate = date(year: 2022, month: 5, day: 5)                 // 2022-05-05 22:22:22 +0000
let repeat1 = calendar.nextDate(after: startDate, option: option)! // 2022-05-10 22:22:22 +0000
let repeat2 = calendar.nextDate(after: repeat1, option: option)!   // 2022-08-09 22:22:22 +0000
let repeat3 = calendar.nextDate(after: repeat2, option: option)!   // 2022-11-08 22:22:22 +0000
let repeat4 = calendar.nextDate(after: repeat3, option: option)!   // 2023-02-14 22:22:22 +0000
let repeat5 = calendar.nextDate(after: repeat4, option: option)!   // 2023-05-09 22:22:22 +0000
