## Communication



- If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/cosmicmind). (Tag 'cosmicmind')

- If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/cosmicmind).

- If you **found a bug**, _and can provide steps to reliably reproduce it_, open an issue.

- If you **have a feature request**, open an issue.

- If you **want to contribute**, submit a pull request.



## Installation



> **Embedded frameworks require a minimum deployment target of iOS 8.**

> - [Download Graph](https://github.com/CosmicMind/Graph/archive/master.zip)



## CocoaPods



[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:



```bash

$ gem install cocoapods

```



To integrate Graph's core features into your Xcode project using CocoaPods, specify it in your `Podfile`:



```ruby

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '8.0'

use_frameworks!



pod 'Graph', '~> 3.1.0'

```



Then, run the following command:



```bash

$ pod install

```



## Carthage



Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.



You can install Carthage with Homebrew using the following command:



```bash

$ brew update

$ brew install carthage

```

To integrate Graph into your Xcode project using Carthage, specify it in your Cartfile:



```bash

github "CosmicMind/Graph"

```



Run `carthage update` to build the framework and drag the built `Graph.framework` into your Xcode project.



## Changelog



Graph is a growing project and will encounter changes throughout its development. It is recommended that the [Changelog](https://github.com/CosmicMind/Graph/wiki/Changelog) be reviewed prior to updating versions.



# Samples



The following are samples to see how Graph may be used within your applications.



* Visit the [Samples](https://github.com/CosmicMind/Samples) repo to see example projects using Graph.



## Creating an Entity for an ImageCard



An **Entity** is a model (data) object that represents a **person**, **place**, or **thing**. It may store property values, be a member of groups, and can be tagged.



In the following example, we create an ImageCard view using Material and populate it's properties with an Entity that stores the data for that view.



![Material ImageCard](http://www.cosmicmind.com/gifs/white/image-card.gif)



#### Creating data



```swift

let graph = Graph()



let entity = Entity(type: "ImageCard")

entity["title"] = "Graph"

entity["detail"] = "Build Data-Driven Software"

entity["content"] = "Graph is a semantic database that is used to create data-driven applications."

entity["author"] = "CosmicMind"

entity["image"] = UIImage.load(contentsOfFile: "frontier", ofType: "jpg")



graph.sync()

```



#### Setting the view's properties



```swift

imageCard.toolbar?.title = entity["title"] as? String

imageCard.toolbar?.detail = entity["detail"] as? String

imageCard.imageView?.image = entity["image"] as? UIImage



let contentLabel = UILabel()

contentLabel.text = entity["content"] as? String

imageCard.contentView = contentLabel



let authorLabel = UILabel()

authorLabel.text = entity["author"] as? String

imageCard.bottomBar?.centerViews = [authorLabel]

```

## Searching a list of users in realtime



Using the **Search** API is incredibly flexible. In the following example, Search is used to create a live search on user names with a dynamic UI provided by [Material's SearchBar](http://cosmicmind.com/material/searchbar).



![Material SearchBar](http://www.cosmicmind.com/gifs/shared/search-bar-controller.gif)



#### Preparing the search criteria



```swift

let graph = Graph()



let search = Search(graph: graph).for(types: "User").where(properties: "name")

```



#### Asynchronously searching graph



```swift        

search.async { [weak self, pattern = pattern] (users) in



	guard let regex = try? NSRegularExpression(pattern: pattern, options: []) else {

	    return

    }



	var data = [Entity]()



	for user in users {

		if let name = user["name"] as? String {

			let matches = regex.matches(in: name, range: NSRange(location: 0, length: name.utf16.count))



			if 0 < matches.count {

				data.append(user)

			}

		}

	}



	self?.tableView.data = data

}

```
