How to install

CocoaPods

SwifCron is available through CocoaPods

To install it, simply add the following line in your Podfile:

pod 'SwifCron', '~> 2.0.0'

Swift Package Manager

.package(url: "https://github.com/MihaelIsaev/SwifCron.git", from: "2.0.0")

In your target's dependencies add "SwifCron" e.g. like this:

.target(name: "App", dependencies: ["SwifCron"]),

Usage

import SwifCron

do {
    let everyMinuteCron = try SwifCron("* * * * *")
    let everySecondCron = try SwifCron("* * * * * *")

    //for getting next date related to current date
    let nextMinuteDate = try everyMinuteCron.next()
    let nextSecondDate = try everyMinuteCron.next()

    //for getting next date related to custom date
    let nextDate = try cron.next(from: Date())
} catch {
    print(error)
}

Limitations

This library support both 5 or 6 parts expressions.

With 6 parts format is Second Minute Hour Day of month Month Day of week

For creating expressions you can use this 5-parts or 6-parts (year not supported) generator

I use CrontabGuru as a reference

So you could parse any expression which consists of digits with * , / and - symbols

ToDo

• write more tests
• support literal names of months and days of week in expression
• support non-standard digits like 7 for Sunday in day of week part of expression
