If you already have installed Graphite and loaded your project in it and want to use ION to test your app, you do not need to build and scan Barcode. You simply need to connect your iPad to your computer and wait for Graphite to show it as connected. Then when you start Icenium ION on your iPad, it would automatically load your project.
Still to clear any confusion, I would explain about the Barcode purpose as well (mainly used with Mist to build your app) - once you read the QR code and it is recognized as URL, you need to click on that URL, so that your device downloads the project from our servers and loads it in ION. The Hello World demo is installed along with Icenium ION by default. For more information, refer to our documentation:
