Intro to ARKit
summary
Bootstraps an ARKit Swift project end-to-end: add an Info.plist camera privacy string, import ARKit, wire an ARSCNView outlet and start ARWorldTrackingConfiguration to get device pose; create SCNNodes with SCNGeometry (sphere radius 0.3 m), position with SCNVector3, apply diffuse and specular textures (downloaded from solar systemscope.com) and enable default lighting; attach a repeating SCNAction (repeatForever) to spin the planet — everything runs and produces a rotatable 3D earth in the live camera feed.
