RealityKit – Set text programmatically of an Entity of Reality Composer

Question

In my iOS app I want to introduce a part of AR using the new Reality Composer.

In my project I load a scene with this code:

let arView = ARView.init(fram

In RealityKit framework, use the following type method for generating 3D text:

static func generateText(_ string: String, 
                   extrusionDepth: Float, 
                             font: MeshResource.Font, 
                   containerFrame: CGRect, 
                        alignment: CTTextAlignment, 
                    lineBreakMode: CTLineBreakMode) -> MeshResource

Let's see how a real code looks like:

let textAnchor = try! SomeText.loadTextScene()

let textEntity: Entity = textAnchor.vacation!.children[0].children[0]

var textModelComponent: ModelComponent = (textEntity.components[ModelComponent])!

textModelComponent.mesh = .generateText("Hello, World!",
                         extrusionDepth: 0.5,
                                   font: .systemFont(ofSize: 0.25),
                         containerFrame: CGRect.zero,
                              alignment: .center,
                          lineBreakMode: .byCharWrapping)

textAnchor.vacation!.children[0].children[0].components.set(textModelComponent)
arView.scene.anchors.append(textAnchor)
