#### Modern Swifty API for `NSTimer`
###### SwiftyTimer allows you to instantly schedule delays and repeating timers using convenient closure syntax. It's time to get rid of Objective-C cruft.
Read [Swifty APIs: NSTimer](http://radex.io/swift/nstimer/) for more information about this project.
## Usage
You can easily schedule repeating and non-repeating timers (repeats and delays) using `Timer.every` and `Timer.after`:
```swift
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:
```swift
100.ms
1.second
2.5.seconds
5.seconds
10.minutes
1.hour
2.days
```
You can pass method references instead of closures:
```swift
Timer.every(30.seconds, align)
```
### Manual scheduling
If you want to make a timer object without scheduling, use `new(after:)` and `new(every:)`:
```swift
let timer = Timer.new(every: 1.second) {
println(self.status)
}
```
(This should be defined as an initializer, but [a bug in Foundation](http://www.openradar.me/18720947) prevents this)
Call `start()` to schedule timers created using `new`. You can optionally pass the run loop and run loop modes:
```swift
timer.start()
timer.start(modes: .defaultRunLoopMode, .eventTrackingRunLoopMode)
```
### Invalidation
If you want to invalidate a repeating timer on some condition, you can take a `Timer` argument in the closure you pass in:
```swift
Timer.every(5.seconds) { (timer: Timer) in
// do something
if finished {
timer.invalidate()
}
}
```
## Installation
**Note:** If you're running Swift 2, use [SwiftyTimer v1.4.1](https://github.com/radex/SwiftyTimer/tree/1.4.1)
#### CocoaPods
If you're using CocoaPods, just add this line to your Podfile:
```ruby
pod 'SwiftyTimer'
```
Install by running this command in your terminal:
```sh
pod install
```
Then import the library in all files where you use it:
```swift
import SwiftyTimer
```
#### Carthage
Just add to your Cartfile:
```ruby
github "radex/SwiftyTimer"
```
#### Manually
Simply copy `Sources/SwiftyTimer.swift` to your Xcode project.
