Font issue In AR view

Hi,

In AR view many fonts are not getting applied, any solution for this or this is known issue? I am using ARKit + scene kit.



func addtextnode() {

let physicsBody = SCNPhysicsBody(type: .static, shape: nil)

let textGeometry = SCNText(string: "My String", extrusionDepth: 0.8)

textGeometry.font = UIFont(name: "PermanentMarker-Regular", size: 1)

textGeometry.firstMaterial!.diffuse.contents = UIColor.init(red: 27/255, green: 98/255, blue: 52/255, alpha: 1)

let (min, max) = textGeometry.boundingBox

let dx = min.x + 0.5 * (max.x - min.x)

let dy = min.y + 0.5 * (max.y - min.y)

let dz = min.z + 0.5 * (max.z - min.z)

let centertextnode = SCNNode(geometry: textGeometry)

centertextnode.pivot = SCNMatrix4MakeTranslation(dx, dy, dz)

centertextnode.worldPosition = SCNVector3(0.01,0.2,-1.2)

centertextnode.scale = SCNVector3(0.1,0.1,0)

centertextnode.physicsBody = physicsBody

scnview.scene.rootNode.addChildNode(centertextnode)

}
