Installation
Embedded frameworks require a minimum deployment target of iOS 8.
CocoaPods
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
To integrate Graph’s core features into your Xcode project using CocoaPods, specify it in your Podfile:
source ‘https://github.com/CocoaPods/Specs.git’
platform :ios, ‘8.0’
use_frameworks!
pod ‘Graph’, ‘~> 3.1.0’
Then, run the following command:
$ 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:
$ brew update
$ brew install carthage
To integrate Graph into your Xcode project using Carthage, specify it in your Cartfile:
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 be reviewed prior to updating versions.
Samples
The following are samples to see how Graph may be used within your applications.
- Visit the 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.
Creating data
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
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.
Preparing the search criteria
let graph = Graph()
let search = Search<Entity>(graph: graph).for(types: “User”).where(properties: “name”)
Asynchronously searching graph
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
}
