hope this fix your issue Two nodes, The text and board are separated. I want the board to be the background for the text. , You're adding the panelNode as a child node of your text here:
sphereNode.addChildNode(panelNode)
box.position = SCNVector3(0.1, 0.1, -0.1)
box.position = SCNVector3(w/2, h, 0)

Locations in iPhone ARKit overlapping at one place

Does that help There were no issue in my code, the issue was in server and it was giving me all the data for same geo location. Once I started getting data with different geo locations, my problem was solved.

How to get Child Nodes position using Scenekit - ARKit in iOS 11?

it fixes the issue The position of a node is always relative to another node, at the very least the scene’s rootNode. To get a childnode’s position relative to the rootnode (i.e. the position in world space) you can use convertPosition to: rootNode. To get the position of a childnode relative to the parent you can convert the position to the parent node’s space.

hitTest(_:options:) don't recognize nodes behind ARKit planes

To fix the issue you can do I believe what you need to do is change your SCNHitTestSearchModeparameter which allows you to set:
static let searchMode: SCNHitTestOption
case all
case any
case closest
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

    //1. Get The Current Touch Location
    guard let currentTouchLocation = touches.first?.location(in: self.augmentedRealityView) else { return }

    //2. Perform An SCNHitTest Setting The SearchMode To 1 (All) Which Returns A List Of Results Sorted From Nearest To Farthest
    if #available(iOS 11.0, *) {

        let hitTestResults = self.augmentedRealityView.hitTest(currentTouchLocation, options: [SCNHitTestOption.searchMode: 1])

        //3. Loop Through The Results & Get The Nodes
        for index in 0..<hitTestResults.count{

            let node = hitTestResults[index]
            print(node)

        }
    }
}

Exchange nodes of 3D Model in ARKit

This might help you SCNNode and the node tree work analogously to UIView and the view tree, so instead of trying to set the existing node equal to something else you should:
Get the parent node of the target with parent Remove the target node with removeFromParentNode() Add the new child node to the parent with addChildNode(_:)

Add plane nodes to ARKit scene vertically and horizontally

I hope this helps you . Solved! Here's how to make the view "parallel" to the camera at all times:
let yourNode = SCNNode()

let billboardConstraint = SCNBillboardConstraint()
billboardConstraint.freeAxes = [.X, .Y, .Z]
yourNode.constraints = [billboardConstraint]
guard let currentFrame = sceneView.session.currentFrame else {return nil}
let camera = currentFrame.camera
let transform = camera.transform
var translationMatrix = matrix_identity_float4x4
translationMatrix.columns.3.z = -0.1
let modifiedMatrix = simd_mul(transform, translationMatrix)
let node = SCNNode(geometry: plane)
node.simdTransform = modifiedMatrix
