You can also subdivide your Geometry:

You didn't explain what the problem is, but I'm going to guess that nothing happens and then the label gets update (finally) to the last value.

That's because sceneTapped is a gesture recognizer, which mean it's running on the main thread. (All UI code and event handling runs on the main thread.)

So sceneTapped is spinning in a loop, on the main thread, queuing up blocks to run on the main thread. But the main thread is busy running sceneTapped so none of those blocks execute.

Finally, sceneTapped returns, and all of those queued blocks suddenly execute, one after the other.

If this for loop is a long running loop, it needs to be running in its own thread. As a rule, you never want to have any code that takes a significant amount to time to execute to be running on the main thread. Any code that blocks the main thread freezes your UI and all user interaction.

So basically you should have something like this:

That is probably because it is not finding the texture images. Are the images in your bundle?

Or did you forget to include the images in your target?

I found out the root cause of the issue. The issue was related to the Model which I was using for AR. When, I replaced the model with the one provided in this link:- https://developer.apple.com/augmented-reality/quick-look/. I was not facing any issues. So, if anyone face such type of issues in future I would recommend to use any of the model provided by Apple to check if the issue persists with it or not.

To pass data to updateNSView(_:context:) or updateUIView(_:context:) instance method you need to create @State and @Binding properties.

Use the following code to find out how to do it:

I've written this code for macOS but you can easily change it for iOS:

The sphere is manually placed at (0, 0, 0) and so is the light (default value). This means that the light is placed inside the sphere. This means that the surface of the sphere is facing away from the light source and thus isn't lit.

Not much to change - just instead of UIViewRepresentable conform to NSViewRepresentable, and similar replacements from AppKit instead of UIKit

Here it is (tested with Xcode 11.2):

SCNCamera has a zFar property, the default value is 100, any surface further away from the camera than this is clipped to improve performance. In your screenshot the leg is the furthest part of the model from the camera so gets clipped first, and as you move further away the whole model is clipped. You can just increase the zFar to a number suitable for your scene.
