Je serais surpris s'il n'y a pas une meilleure réponse que celle-ci, mais je n'en ai pas trouvé une, alors voici ce que j'ai.
extension SCNNode {
func boundingBoxContains(point: SCNVector3, in node: SCNNode) -> Bool {
let localPoint = self.convertPosition(point, from: node)
return boundingBoxContains(point: localPoint)
}
func boundingBoxContains(point: SCNVector3) -> Bool {
return BoundingBox(self.boundingBox).contains(point)
}
}

let min: SCNVector3
let max: SCNVector3
init(_ boundTuple: (min: SCNVector3, max: SCNVector3)) {

max = boundTuple.max
}

let contains =
min.x <= point.x &&
min.y <= point.y &&
min.z <= point.z &&
max.x > point.x &&
max.y > point.y &&
max.z > point.z
return contains
