`anim` is an animation library written in Swift with a simple, declarative API in mind.
```swift
// moves box to 100,100 with default settings
anim {
self.box.frame.origin = CGPoint(x:100, y:100)
}
// after that, waits 100 ms
.wait(0.1)
// moves box to 0,0 after waiting
.then {
self.box.frame.origin = CGPoint(x:0, y:0)
}
// displays message after all animations are done
.callback {
print("Just finished moving 📦 around.")
}
```
It supports a bunch of easing functions and chaining multiple animations. It's a wrapper on Apple's `UIViewPropertyAnimator` on its core, and falls back to `UIView.animate` on versions before iOS and tvOS 10.
It uses `NSAnimationContext` on macOS.
#### Examples
Example projects are available at `examples/` folder and as targets on XCode project.
---
#### Cocoapods
```ruby
pod 'anim'
```
#### Carthage
```ogdl
github "onurersel/anim"
```
#### Manually
Or simply drag the swift files inside `src/` folder into your project.

For complete documentation, visit [http://onurersel.github.io/anim/](http://onurersel.github.io/anim/).
Initialize animations with `anim` constructor.
```swift
// Initialize with default settings
anim {
// animation block
}
```
```swift
// or initialize with it's own settings
anim { (settings) -> (animClosure) in
settings.delay = 1
settings.duration = 0.7
settings.ease = .easeInOutBack
return {
// animation block
}
}
```
```swift
// or initialize layout constraint animations just by passing the parent view
anim(constraintParent: self.view) {
// animation block
}
anim(constraintParent: self.view) { (settings) -> (animClosure) in
// settings...
return {
// animation block
}
}
// you don't need to call layoutIfNeeded() before or inside the
// animation blocks, it's handled by anim
//
// for example to update constant value of a constraint,
// you can just change it inside the animation block
let width: NSLayoutConstraint //...
anim(constraintParent: self.view) {
width.constant = 100 // new value
}
// that's it!
```
Chain animations with `then` function.
```swift
anim {}
.then{
// next animation block
}
```
```swift
anim {}
.then { (settings) -> animClosure in
settings.duration = 1
return {
// next animation block
}
}
```
```swift
anim {}
.then(constraintParent: self.view) {
// chaining constraint animations
}
.then(constraintParent: self.view) { (settings) -> animClosure in
settings.duration = 1
return {
// next animation block for constraints
}
}
```
Wait between animation steps with `wait` function.
```swift
anim{}.wait(0.25).then{} //...
```
Insert callbacks between animation steps with `.callback` function.
```swift
anim{}
.callback {
// custom block
}
.then{} //...
```
Stop animations with `stop` function.
```swift
let animation = anim{}.then{} // ...
animation.stop()
```
#### Default settings
You can change default animation settings through `anim.defaultSettings` property.
```swift
anim.defaultSettings.ease = .easeInOutCubic
```
#### Easing
`anim.Ease` exposes a bunch of easing options.
