## Pull Request Submissions.
All pull requests should be made to the development branch. Details should be available describing your fix. Before submitting a pull request, please confirm that merge issues are resolved.
<a href="#asking-questions"></a>
## Asking Questions
We don't use GitHub as a support forum.
For any usage questions that are not specific to the project itself,
please ask on [Stack Overflow](http://stackoverflow.com/questions/tagged/cosmicmind) instead.
By doing so, you'll be more likely to quickly solve your problem,
and you'll allow anyone else with the same question to find the answer.
This also allows maintainers to focus on improving the project for others.
<a href="#reporting-security-issues"></a>
## Reporting Security Issues
CosmicMind takes security seriously.
If you discover a security issue, please bring it to our attention right away!
Please **DO NOT** file a public issue,
instead send your report privately to <support@cosmicmind.com>.
This will help ensure that any vulnerabilities that _are_ found
can be [disclosed responsibly](http://en.wikipedia.org/wiki/Responsible_disclosure)
to any affected parties.
<a href="#reporting-other-issues"></a>
## Reporting Other Issues
A great way to contribute to the project
is to send a detailed issue when you encounter an problem.
We always appreciate a well-written, thorough bug report.
Check that the project issues database
doesn't already include that problem or suggestion before submitting an issue.
If you find a match, add a quick "+1" or "I have this problem too."
Doing this helps prioritize the most common problems and requests.
When reporting issues, please include the following:
* The version of Xcode you're using
* The version of iOS you're targeting
* The full output of any stack trace or compiler error
* A code snippet that reproduces the described behavior, if applicable
* Any other details that would be useful in understanding the problem
This information will help us review and fix your issue faster.

# Motion
Welcome to **Motion,** a library used to create beautiful animations and transitions for views, layers, and view controllers.
## Photos Sample
Take a look at a sample [Photos](https://github.com/CosmicMind/Samples/tree/master/Projects/Programmatic/Photos) project to get started.
![Photos](http://www.cosmicmind.com/motion/projects/photos.gif)
* [Photos Sample](https://github.com/CosmicMind/Samples/tree/master/Projects/Programmatic/Photos)
### Who is Motion for?
Motion is designed for beginner to expert developers. For beginners, you will be exposed to very powerful APIs that would take time and experience to develop on your own, and experts will appreciate the time saved by using Motion.
### What you will learn
You will learn how to use Motion with a general introduction to fundamental concepts and easy to use code snippets.
# Transitions
Motion transitions a source view to a destination view using a linking identifier property named `motionIdentifier`.
| Match | Translate | Rotate | Arc | Scale |
|:---:|:---:|:---:|:---:|:---:|
| ![Match](http://www.cosmicmind.com/motion/transitions_identifier/match.gif) | ![Translate](http://www.cosmicmind.com/motion/transitions_identifier/translate.gif) | ![Rotate](http://www.cosmicmind.com/motion/transitions_identifier/rotate.gif) | ![Arc](http://www.cosmicmind.com/motion/transitions_identifier/arc.gif) | ![Scale](http://www.cosmicmind.com/motion/transitions_identifier/scale.gif) |
### Example Usage
An example of transitioning from one view controller to another with transitions:
#### View Controller 1
```swift
greyView.motionIdentifier = "foo"
orangeView.motionIdentifier = "bar"
```
#### View Controller 2
```swift
isMotionEnabled = true
greyView.motionIdentifier = "foo"
orangeView.motionIdentifier = "bar"
orangeView.transition(.translate(x: -100))
```
The above code snippet tells the source views in `view controller 1` to link to the destination views in `view controller 2` using the `motionIdentifier`. Animations may be added to views during a transition using the **transition** method. The *transition* method accepts MotionTransition structs that configure the view's animation.
* [MotionTransition API](https://cosmicmind.gitbooks.io/motion/content/motion_transition_api.html)
* [Code Samples](https://github.com/CosmicMind/Samples/tree/master/Projects/Programmatic/TransitionsWithIdentifier)
## UINavigationController, UITabBarController, and UIViewController Transitions
Motion offers default transitions that may be used by UINavigationControllers, UITabBarControllers, and presenting UIViewControllers.
| Push | Slide | ZoomSlide | Cover | Page | Fade | Zoom |
|:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| ![Push](http://www.cosmicmind.com/motion/transitions/push.gif) | ![Slide](http://www.cosmicmind.com/motion/transitions/slide.gif)| ![Zoom Slide](http://www.cosmicmind.com/motion/transitions/zoom_slide.gif) | ![Cover](http://www.cosmicmind.com/motion/transitions/cover.gif) | ![Page](http://www.cosmicmind.com/motion/transitions/page_in.gif) | ![Fade](http://www.cosmicmind.com/motion/transitions/fade.gif) | ![Zoom](http://www.cosmicmind.com/motion/transitions/zoom.gif)|
### Example Usage
An example of transitioning from one view controller to another using a UINavigationController with a zoom transition:
#### UINavigationController
```swift
class AppNavigationController: UINavigationController {
open override func viewDidLoad() {
super.viewDidLoad()
isMotionEnabled = true
motionNavigationTransitionType = .zoom
}
}
```
To add an automatic reverse transition, use `autoReverse`.
```swift
motionNavigationTransitionType = .autoReverse(presenting: .zoom)
```
* [Code Samples](https://github.com/CosmicMind/Samples/tree/master/Projects/Programmatic/Transitions)
# Animations
Motion provides the building blocks necessary to create stunning animations without much effort. Motion's animation API will make maintenance a breeze and changes even easier. To create an animation, use the **animate** method of a view or layer and pass in a list of MotionAnimation structs. MotionAnimation structs are configurable values that describe how to animate a property or group of properties.
| Background Color | Corder Radius | Fade | Rotate | Size | Spring |
|:---:|:---:|:---:|:---:|:---:|:---:|
| ![Background Color](http://www.cosmicmind.com/motion/animations/background_color.gif) | ![Corner Radius](http://www.cosmicmind.com/motion/animations/corner_radius.gif) | ![Fade](http://www.cosmicmind.com/motion/animations/fade.gif) | ![Rotate](http://www.cosmicmind.com/motion/animations/rotate.gif) | ![Size](http://www.cosmicmind.com/motion/animations/size.gif) | ![Spring](http://www.cosmicmind.com/motion/animations/spring.gif) |
| Border Color & Border Width | Depth | Position | Scale | Spin | Translate |
|:---:|:---:|:---:|:---:|:---:|:---:|
|![Border Color & Border Width](http://www.cosmicmind.com/motion/animations/border_color.gif) | ![Depth](http://www.cosmicmind.com/motion/animations/depth.gif) | ![Position](http://www.cosmicmind.com/motion/animations/position.gif) | ![Scale](http://www.cosmicmind.com/motion/animations/scale.gif) | ![Spin](http://www.cosmicmind.com/motion/animations/spin.gif) | ![Translate](http://www.cosmicmind.com/motion/animations/translate.gif) |
### Example Usage
```swift
let box = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
box.backgroundColor = .blue
box.animate(.background(color: .red), .rotate(180), .delay(1))
```
In the above code example, a box view is created with a width of 100, height of 100, and an initial background color of blue. Following the general creation of the view, the _Motion animate_ method is passed _MotionAnimation structs_ that tell the view to animate to a red background color and rotate 180 degrees after a delay of 1 second. That's pretty much the general idea of creating animations.
