This project is a basic example of using MultipeerConnectivity within ARKit2 to share ARWorldMaps and ARAnchors across multiple devices.

All the code is fully commented so the apps functionality should be clear to everyone.

Branches:

The Master Branch was originally compiled in XCode10 Beta using Swift 4.

An updated Branch called 'Swift4.2' contains the project built in XCode 10.5 Beta and uses Swift 4.2.

Requirements:

The project is setup for iPhone, and in Landscape Orientation.

Core Functionality:

The application automatically creates an MCSession which can be found in ARCloudShare.swift and shares ARWorldMaps and ARAnchors in real time.

Using NSKeyedArchiver and NSKeyedUnarchiver the users can rotate (using a UIPanGestureRecognizer), scale (using UIPinchGestureRecognizer), and change the colours of each of the faces of a single SCNBox using a UITapGestureRecognizer.

For the purpose of this application, I have only allowed placement of one Cube but this can easily be adapted to meet your needs.

The cube can only be placed on a detected ARPlaneAnchor, which again can easily be customised as per your needs.

The core idea behind this app, was a basic comparison between the functionality of Google Cloud Anchors, and ARKit, with ARKit winning easily.

To change the colour of one of the faces of the cube, you need to double tap on the face and then select one of the colours from the bottom menu.
