ReadSwifty APIs: NSTimer for more information about this project.

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

Timer.every(0.7.seconds){    statusItem.blink()}Timer.after(1.minute){println("Are you still here?")}

You can specify time intervals with these intuitive helpers:

100.ms1.second2.5.seconds5.seconds10.minutes1.hour2.days

You can pass method references instead of closures:

Timer.every(30.seconds, align)

If you want to make a timer object without scheduling, usenew(after:) andnew(every:):

lettimer=Timer.new(every:1.second){println(self.status)}

(This should be defined as an initializer, buta bug in Foundation prevents this)

Callstart() to schedule timers created usingnew. You can optionally pass the run loop and run loop modes:

timer.start()timer.start(modes:.defaultRunLoopMode,.eventTrackingRunLoopMode)

If you want to invalidate a repeating timer on some condition, you can take aTimer argument in the closure you pass in:

Timer.every(5.seconds){(timer:Timer)in    // do somethingif finished{        timer.invalidate()}}

Note: If you're running Swift 2, useSwiftyTimer v1.4.1

If you're using CocoaPods, just add this line to your Podfile:

pod'SwiftyTimer'

Install by running this command in your terminal:

pod install

Then import the library in all files where you use it:

import SwiftyTimer

Just add to your Cartfile:

github"radex/SwiftyTimer"

Simply copySources/SwiftyTimer.swift to your Xcode project.

If you like SwiftyTimer, check outSwiftyUserDefaults, which applies the same swifty approach toNSUserDefaults.

You might also be interested in my blog posts which explain the design process behind those libraries:
