Augmented Reality component for iOS, written in Swift 2.0. Note: Version 0.1.0 was written in Swift 1.2 so use that for older Xcodes.

• Fully customisable annotation views
• Automatic vertical stacking of annotations views
• Tracks user movement and updates visible annotations
• Works on all iOS devices(with GPS) and supports all rotations
• Works with large amount of annotations and on-screen annotation views
• iOS 7+
• Easy debugging with map controller
• Simple and easy to use

• CoreLocation.Framework
• CoreMotion.Framework
• MapKit.Framework (For debugging only, can be set ‘Optional’)

Xcode 6.3 is needed for Swift 1.2.

• Drag & drop HDAugmentedReality folder from demo project into your project.
• Add native frameworks listed in “Dependencies & Requirements”
• iOS 8: Add NSLocationWhenInUseUsageDescription to Info.plist. This is needed for location authorization.

• Works only on iOS8+ because swift pod is built as dynamic framework and dynamic frameworks don't work on iOS7
• iOS 8: Add NSLocationWhenInUseUsageDescription to Info.plist. This is needed for location authorization.
• Add this two lines to your podfile:

use_frameworks!
pod 'HDAugmentedReality', :git => 'https://github.com/DanijelHuis/HDAugmentedReality.git'

Setup controller and provide annotations:

var arViewController = ARViewController()
arViewController.debugEnabled = true
arViewController.dataSource = self
arViewController.maxDistance = 0
arViewController.maxVisibleAnnotations = 100
arViewController.maxVerticalLevel = 5
arViewController.headingSmoothingFactor = 0.05
arViewController.trackingManager.userDistanceFilter = 25
arViewController.trackingManager.reloadDistanceFilter = 75

arViewController.setAnnotations(dummyAnnotations)
self.presentViewController(arViewController, animated: true, completion: nil)

Implement ARDataSource and provide annotation views:

func ar(arViewController: ARViewController, viewForAnnotation: ARAnnotation) -> ARAnnotationView
{
// Annotation views should be lightweight views, try to avoid xibs and autolayout all together.
var annotationView = TestAnnotationView()
annotationView.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.5)
annotationView.frame = CGRect(x: 0,y: 0,width: 150,height: 50)
return annotationView;
}

Annotation views must subclass ARAnnotationView. Override bindUi method inside your custom annotation view to set your UI.

Make sure NSLocationWhenInUseUsageDescription is added to your Info.plist file.
