How do we download the beta version of the tool?
Downloading the Beta
Which tool? Apple software betas?
You can download the demo app presented at WWDC 2022 from this link: https://developer.apple.com/documentation/roomplan/create_a_3d_model_of_an_interior_room_by_guiding_the_user_through_an_ar_experience/
There is a blue download button at the top of the docs.
You will also need Xcode 14 beta, Mac OS 12.4 (min. OS required by Xcode) and a PHYSICAL iPhone/iPad with a LiDAR sensor. So an iPhone 12/13 Pro or the latest iPad Pro models that have LiDAR.
