Installation

Embedded frameworks require a minimum deployment target of iOS 8.

• Download Graph

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
}

graph's Issues

Enhance Search

• Allow Type to property and group values
• order by values

Session completionHandlers aren't being called on main thread

Update removeValueForKey to return a structure of removed values.

Add Bond Nodes to Kit

Should probably change the name of this repo...

Update to GKGraphKit 3 with GKAlgoKit Support

Fix XCTest so it runs locally

Update your read me

Very unclear which .xcodeproj you should be using

Document GK3 Data Structures

Add property handling for Nodes

Add network interface - Bridge

Update boolean property checks to use "is" format.

Format code documentation for parser and tooltips

Add Actions / Bonds and refactor base code

Add exclusive to OrderedSet and OrderedMultiSet

Add Property values to a Set for both Entity and Action

Protocol-oriented expected

Great job. However, the interface with so many classes are a bit hard to understand the structure and relationship, for beginners.

Also from match-perspective, someone, like myself, expect a Swift framework that present Graph with its match abstraction, and focus on graph math operations and algorithms. Rather than, this seems to me more CoreData/storage focused.

Could you please consider this as new features for GraphKit? Thanks

Add CreatedDate to println description for Entity, Action, and Bond

Line Chart Crashes if it only has equal values for a line

I have a chart with a single line
I set startFromZero as true
I set data values to [0,0]

you then get

*** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [20 nan]'

Caused by

• (CGFloat)_positionYForLineValue:(CGFloat)value {
  CGFloat scale = (value - [self _minValue]) / ([self _maxValue] - [self _minValue]);

because ([self _maxValue] - [self _minValue]) == 0

Add OrderedDictionary and OrderedMultiDictionary data structure

This will replace the return Tree and MultiTree structure in Graph, Action, Bond, and Entity.

Add ordering to result set in graph search.

Best way of searching entity.

Hi, first off, I would like to say that I love the concept. I've been using it for a few days and I would like to ask if there is an optimized way that you'd recommend for searching for a specific entity with a specific property. I've been time profiling the app I'm using and for comparing 350 entities that already exist in the Graph, its taking roughly 10 seconds.

Action complete methods for Subjects and Objects

Type 'GKEntity' does not conform to protocol 'SequenceType'

func logEntity(entity: GKEntity) {
for (key, value) in entity {
println("Key: (key) Value: (value)")
}
}

Update intersectInPlace to not use intersect method

Add OrderedSet and OrderedMultiSet and Initial Probability

This should also be used with groups

Xcode 6.2 and iOS 8.2 compatibility

Apple just released their new public versions of Xcode and iOS. Can you please update your library / pod to support the latest release. Thanks.

Maybe a bug, But more likely something im doing wrong

private func internalSelect(x: RedBlackNode<Key, Value>, order: Int) -> RedBlackNode<Key, Value> {
    validateOrder(order)
    var r: Int = x.left.order + 1
    if order == r {
        return x
    } else if order < r {
        return internalSelect(x.left, order: order)
    }
    return internalSelect(x.right, order: order - r)
}

I keep getting " fatal error: unexpectedly found nil while unwrapping an Optional value
(lldb) "

Seems to happen after hitting this line of code in my project
var randomWordFromWords = graph.search(Entity: "Word")[randomNumber()]

Allow GK structures to be stored as properties within Entity, Action, Bonds -> like Array, Set ... etc.

Add convenience dictionary method to Sorted*Dictionary

Add Reachability to Network

Add indexOf to OrderedSet and OrderedMultiSet

Add reverse index for ordered Structures

Add post method to Session

Cache property and group values

This will be a performance gain. :)

Add iCloud Support

Add group mapping for Entity and Action Classes

Update GraphKit to use Generic Programming

Add Comparable to OrderedSet, OrderedMultiSet, Tree, and math operator operations.

Add named graphs.

Write query engine for Graph.

Update README for GK4.

Create inverse relationship from Entity to Action

Add search support through Graph

Add boolean value search or possibly allow AnyObject search

Add keys and values property to Ordered*Dictionary

Refine Entity, Action, Bond to reusable components.

Format documentation to new swift xcode standards

Expand code parser to include multiple templates
