ios – Swift add custom geometry (view) to scnnode in SceneKit

I have an interactive globe built with SceneKit. The globe is a SCNNode and the dots that represent land are also SCNNodes and are children of the globe. I want to add a custom view as the geometry for one of the children of the globe. I know how to add a node with a spherical geometry and change its color and so on. Im not sure how to use a custom view (swift ui) for the geometry of a node.

 let lowerCircle = SCNSphere(radius: dotRadius * 5)
 lowerCircle.firstMaterial?.diffuse.contents = GenericColor(cgColor: UIColor.white.cgColor)
 lowerCircle.firstMaterial?.lightingModel = SCNMaterial.LightingModel.constant

 let dotNode = SCNNode(geometry: lowerCircle)
                    
 dotNode.name = "NewYorkDot"
 dotNode.position = textureMap[i].position
 positions.append(dotNode.position)
 dotNodes.append(dotNode)
