Interacting with Augmented Reality Content in .NET MAUI on iOS

Overlaying nodes is just the first step in an AR app — users expect to interact with them. David Britch shows how to place an image on a scene in a .NET MAUI iOS app and manipulate it with gesture recognizers.

What you’ll learn

• Overlaying an image — creating an ImageNode from an SCNPlane with a billboard constraint so it faces the camera
• Adding gesture recognizers — wiring up tap, pinch, and pan recognizers on the ARSCNView
• Hit testing nodes — determining which node a gesture landed on
• Manipulating nodes — removing a node on tap, scaling it with pinch, and moving it with pan
• Cleaning up — removing gesture recognizers when there’s no node to interact with
