ARSCNPlaneGeometry update and re-calculate texture coordinates, instead of stretching them - scenekit

Question

I'm having a problem on the texture coordinates of planes geometries being updated by ARKit. Texture images get stretched, I want to avoid that.
Right now I'm detecting horizontal and vertical walls and applying a texture to them. It's working like a charm...
But when the geometry gets updated because it extents the detection of the wall/floor, the texture coordinates get stretched instead of re-mapping, causing the texture to look stretched like image below.
You can also see an un-edited video of the problem happening: https://www.youtube.com/watch?v=wfwYPwzND74
This is the piece of code where the geometry gets updated:
func renderer(_ renderer: SCNSceneRenderer, didUpdate node: SCNNode, for anchor: ARAnchor) {
guard let planeAnchor = anchor as? ARPlaneAnchor else {
return
}
let planeGeometry = ARSCNPlaneGeometry(device: device)!
planeGeometry.update(from: planeAnchor.geometry)
//I suppose I need to do some texture re-mapping here.
planeGeometry.materials = node.geometry!.materials
node.geometry = planeGeometry
}
I have seen that you can define the texture coordinates by defining it as a source like this:
let textCords = [] //Array of coordinates
let uvData = Data(bytes: textCords, count: textCords.count * MemoryLayout<vector_float2>.size)
let textureSource = SCNGeometrySource(data: uvData,
semantic: .texcoord,
vectorCount: textCords.count,
usesFloatComponents: true,
componentsPerVector: 2,
bytesPerComponent: MemoryLayout<Float>.size,
dataOffset: 0,
dataStride: MemoryLayout<vector_float2>.size)
But I have no idea how to fill the textCords array to make it fit correctly accordingly to the updated planeGeometry
Edit:
Re-defining the approach:
Thinking deeply on the problem, I came with the idea that I need to modify the texture's transform to fix the stretching part, but then I have two options if I do that:
Either keep the texture big enough to fill the entire geometry but
keeping a ratio of 1:1 to avoid stretching
Or keep the texture the
original size but with 1:1 aspect ratio and repeat the texture
multiple times to fit the entire geometry.
Any of these approaches I'm still lost of how to do it. What would you suggest?
