The ultimate API for iOS & OS X Auto Layout — impressively simple, immensely powerful. PureLayout extends `UIView`/`NSView`, `NSArray`, and `NSLayoutConstraint` with a comprehensive Auto Layout API that is modeled after Apple's own frameworks. PureLayout is an Objective-C library that also works (and looks!) great with Swift using a bridging header. The ultimate API for iOS & OS X Auto Layout — impressively simple, immensely powerful. PureLayout extends `UIView`/`NSView`, `NSArray`, and `NSLayoutConstraint` with a comprehensive Auto Layout API that is modeled after Apple's own frameworks. PureLayout is a cross-platform Objective-C library that works (and looks!) great in Swift. It is fully backwards-compatible with all versions of iOS and OS X that support Auto Layout.
Writing Auto Layout code from scratch isn't easy. PureLayout provides a fully capable and developer-friendly interface for Auto Layout. It is designed for clarity and simplicity, and takes inspiration from the AutoLayout UI options available in Interface Builder while delivering far more flexibility. The API is also highly efficient, as it adds only a thin layer of third party code and is engineered for maximum performance. Writing Auto Layout code from scratch isn't easy.

## Usage ## Usage
### Example Project ### Sample Code (Swift)
Open the project included in the repository (requires Xcode 6 or higher). It contains [iOS](PureLayout/Example-iOS) (`Example-iOS` scheme) and [OS X](PureLayout/Example-Mac) (`Example-Mac` scheme) demos of the library being used in various scenarios. PureLayout dramatically simplifies writing Auto Layout code. Let's take a quick look at some examples, using PureLayout from Swift.
On iOS, you can use different device simulators and rotate the device to see the constraints in action (as well as toggle the taller in-call status bar in the iOS Simulator). Here's a constraint between two views created (and automatically activated) using PureLayout:
```swift
view1.autoPinEdge(.Top, toEdge: .Bottom, ofView: view2)
```
Without PureLayout, here's the equivalent code you'd have to write using Apple's Foundation API directly:
```swift
NSLayoutConstraint(item: view1, attribute: .Top, relatedBy: .Equal, toItem: view2, attribute: .Bottom, multiplier: 1.0, constant: 0.0).active = true
```
Many APIs of PureLayout create multiple constraints for you under the hood, letting you write highly readable layout code:
```swift
// 2 constraints created & activated in one line!
logoImageView.autoCenterInSuperview()
// 4 constraints created & activated in one line!
textContentView.autoPinEdgesToSuperviewEdgesWithInsets(UIEdgeInsets(top: 20.0, left: 5.0, bottom: 10.0, right: 5.0))
```
PureLayout always returns the constraints it creates so you have full control:
```swift
let constraint = skinnyView.autoMatchDimension(.Height, toDimension: .Width, ofView: tallView)
```
PureLayout supports all Auto Layout features including inequalities, priorities, layout margins, identifiers, and much more. It's a comprehensive, developer-friendly way to use Auto Layout.
Check out the example apps below for many more demos of PureLayout in use.
### Example Apps
Open the project included in the repository (requires Xcode 6 or higher). It contains [iOS](PureLayout/Example-iOS) (`Example-iOS` scheme) and [OS X](PureLayout/Example-Mac) (`Example-Mac` scheme) demos of the library being used in various scenarios. The demos in the iOS example app make a great introductory tutorial to PureLayout -- run each demo, review the code used to implement it, then practice by making some changes of your own to the demo code.
Each demo in the iOS example app has a Swift and Objective-C version. **To compile & run the Swift demos, you must use Xcode 7.0 or higher (Swift 2.0) and choose the `Example-iOS-Xcode7` scheme.** When you run the example app, you can easily switch between using the Swift and Objective-C versions of the demos. To see the constraints in action while running the iOS demos, try using different device simulators, rotating the device to different orientations, as well as toggling the taller in-call status bar in the iOS Simulator.
On OS X, while running the app, press any key to cycle through the demos. You can resize the window to see the constraints in action. On OS X, while running the app, press any key to cycle through the demos. You can resize the window to see the constraints in action.

* Cons: Not the most concise expression of layout code * Cons: Only available in iOS 9.0 and OS X 10.11 and higher; requires manually activating each constraint; no API for creating multiple constraints at once
