I am glad to share with you a lightweight Swift framework for Apple's Auto-Layout. It helps you write readable and compact UI code using simple API.

At first, it was only a few extenstions of `UIView` desiged for some of my commercial projects, but eventually code continued to grow, so I decided to move it to a seperate framework. I hope some of you find it helpful, so feel free to share your feedback and give some stars to EasySwiftLayout!

If you want to report bug or request new feature - open a ticket. I will try my best to cover them as soon as posible.

## Requirements

- iOS 9.0+
- Xcode 9.0+
- Swift 4+

## Documentation

All methods in EasySwiftLayout designed to be self-explaining, but at the same time all of them includes detail description of usage. You can check it both in code by pressing `⌥` key and clicking on the method, and in our [API Cheat Sheet](#api-cheat-sheet) section down below.

## Installation

### CocoaPods

[CocoaPods](https://cocoapods.org) is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate EasySwiftLayout into your Xcode project using CocoaPods, specify it in your `Podfile`:

```ruby
pod 'EasySwiftLayout'
```

### Carthage

[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate EasySwiftLayout into your Xcode project using Carthage, specify it in your `Cartfile`:

```ogdl
github "denandreychuk/EasySwiftLayout"
```

### Swift Package Manager

The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It is in early development, but EasySwiftLayout does support its use on supported platforms.

Once you have your Swift package set up, adding EasySwiftLayout as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.

```swift
dependencies: [
.package(url: "https://github.com/Pimine/EasySwiftLayout.git", .upToNextMajor(from: "1.6.0"))
]
```

### Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate EasySwiftLayout into your project manually.

#### Embedded Framework

- Clone this repo by running:
```bash
$ git clone https://github.com/denandreychuk/EasySwiftLayout.git
```
- Navigate to the project folder and open `EasySwiftLayout.xcodeproj`.
- Select scheme `Build Framework` by pressing `^ + 0` and run it on any device. It will automatically generate for you `EasySwiftLayout.framework` file and open it in `Finder`.
- Move this file to your project folder.
- Select your application in the Project Navigator (blue icon) to navigate to the target configuration window.
- Select the desired target under the "Targets" heading in the sidebar.
- In "General" tab click on the `+` button under the "Embedded Binaries" section (in Xcode 11 it calls `Frameworks, Libraries, and Embedded Content`) and select moved `EasySwiftLayout.framework` file.
- Done.

> The `EasySwiftLayout.framework` is automatically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.

## Usage

### Quick Start

```swift
import EasySwiftLayout

class ViewController: UIViewController {
private let boxView = UIView()

override func viewDidLoad() {
super.viewDidLoad()
addAndLayoutSubviews()
}

private func addAndLayoutSubviews() {
boxView
.add(toSuperview: view)
.centerInSuperview()
.size(toSquareWithSide: 50)
}
}
```

### Example

EasySwiftLayout comes with [project example](https://github.com/denandreychuk/EasySwiftLayout/tree/master/Example). You can check out how easily you can create screens like this with ESL:

- Navigate to the project folder and open `EasySwiftLayout.xcworkspace`.
- Select scheme `iOS Example` by pressing `^ + 0` and just run it on any device.

#### Pin to Superview Methods

Just to remind, let's say you have a view called `MyView`, which has a `UIButton`(loginButton) over it. In this case, `MyView` is a `superview` for `loginButton` and `loginButton` is a subview of `MyView`.

pinEdge(_:toSuperviewEdge:withInset:respectingGuide:usingRelation:priority:)

##### Summary

Pins the edge of the view using the specified type of relation to the given edge of its superview with the inset and priority of the constraint. Optionally respects one of pre-defined Apple's layout guides.

##### Declaration

```swift
func pinEdge(_ edge: ESLEdge, toSuperviewEdge superviewEdge: ESLEdge, withInset inset: CGFloat = .zero, respectingGuide guide: ESLSuperviewGuide = .none, usingRelation relation: NSLayoutConstraint.Relation = .equal, priority: UILayoutPriority = .required) -> Self
```

##### Discussion

- Consider, accordingly to [Apple's documentation](https://apple.co/2PFH9f2), you cannot pin edges with different axis, otherwise it will throw fatal error.

- Use this method only if you want to pin the edge of the view to the opposite margin of its superview, in other cases `pinEdgeToSuperview(_:withInset:usingRelation:priority:)` would be a better approach.

- To make Auto-Layout works properly, it automatically sets view property `translatesAutoresizingMaskIntoConstraints` to `false`.

##### Precondition

- The view should have the superview, otherwise method will have no effect.

- Pin edges with same axis or method will throw fatal error.

##### Parameters

---------- | ---- |------------
edge | `ESLEdge` | The edge of this view to pin.
superviewEdge | `ESLEdge` | The edge of its superview to pin to.
inset | `CGFloat` | The inset between the edge of this view and the edge of its superview.
