SwiftyTimer is a set of extensions to make the NSTimer API cleaner, nicer to use, and at home with Swift's syntax.

Read Swifty APIs: NSTimer for more information about this project.

You can easily schedule repeating and non-repeating timers (repeats and delays) using NSTimer.every and NSTimer.after:

NSTimer.every(0.7.seconds) {
    statusItem.blink()
}

NSTimer.after(1.minute) {
    println("Are you still here?")
}

SwiftyTimer uses closures instead of target/selector/userInfo.

You can specify time intervals with intuitive Ruby on Rails-like helpers:

1.second
2.5.seconds
5.seconds
10.minutes
1.hour

You can pass method references instead of closures:

NSTimer.every(30.seconds, align)

If you want to make a timer object without scheduling, use new(after:) and new(every:):

let timer = NSTimer.new(every: 1.second) {
    println(self.status)
}

(This should be defined as an initializer, but a bug in Swift prevents this)

The simplest way to install this library is to copy Src/SwiftyTimer.swift to your project. There's no step two!

You can also install this library using CocoaPods. Just add this line to your Podfile:

pod 'SwiftyTimer'

Then import library module like so:

import SwiftyTimer

Note that this requires CocoaPods 0.36+, as well as iOS 8 or OS X 10.9+

If you have comments, complaints or ideas for improvements, feel free to open an issue or a pull request.
