SwifCron is available through CocoaPods
To install it, simply add the following line in your Podfile:
pod 'SwifCron', '~> 2.0.0'.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"]),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)
}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
Please feel free to contribute!
- write more tests
- support literal names of months and days of week in expression
- support non-standard digits like
7for Sunday in day of week part of expression
