What is the most elegant and easy way to load and animate .fbx models in Swift 5?
Is this even possible for a simple iOS App?
As far as I know there is ARKit but I don’t want any augmented reality. Just a 3D model inside of my UIView of the format .fbx.

Could you please let me know what the difference between these two 3d models usdz?
when i open the model on iphone 11, i can see the augmented reality
1- With this model the animation works (https://drive.google.com/file/d/1ZH9DCczO-O1CIV3IbSTv21XmNpm6SwXV/view?usp=sharing)
2- With this model the animation dose not work (https://drive.google.com/file/d/1ooAB8q2_4qI7gBSORfDBEd-iC77aSovd/view?usp=sharing)

Is it possible to use SceneKit for GPU accelerated graphics within a cocoa Application?
I'm looking for a way to do 2D animations in a PowerPoint like application, and not sure which direction to take to have GPU accelerated animations.
Picked up xCode about a week ago and went straight into swift with no Objective-C background. Didn't find any information on the topic, hoping to get this answered here.
Your screenshot depicts the template selection in the project creator. What template you use has no impact on what features is possible in your application. It is perfectly possible to create a Cocoa app and simply drag and drop a SCNView and set it to run a SceneKit scene.
That being said, SceneKit or SpriteKit is definitely overkill just for doing "2D animations like in PowerPoint". You should look into Core Animation:

i am new in objective c and in my application i have to draw the 3D image(like carton boy) and rotate it in X axis,Y axis and z axis by using OpenGL ES framework How can i draw the images.someone help me thanks in advance.
If you are making a 3D game in cocos2d project then the 3D parts will have to be loaded using either another framework (like cocos3d) or like you said using OpenGL framework.
cocos3D http://brenwill.com/cocos3d/ works easily with cocos2d and will allow you to load 3d objects and use them in the way you want.
OpenGL framework will be more difficult to understand and use but will give you more flexibility depending on the results you want.
I would solve your question by creating 3D objects in a open source (and free) software like Blender and load them in a cocos3d project, from there, the way to manipulate them the way you want is fairly easy.
I've started to play around with some 3d modelers a while ago. Now I'm curious: How can I bring such an 3D model to the iPhone or iPad, so that I can see it on screen and maybe even rotate it with gestures?
1) What's the best file format for the 3D models?
2) How would I load a particular 3D model file into openGL ES and then render it?
3) How would I apply an material to the polys, i.e. to make the model appear red?
4) Does the model have some sort of center or pivot point where I can rotate it easily around? Or do I need incredible freakin' math skills to transform all the vertecies in 3D space myself? How hard is it to rotate something?
5) Can I scale models or fit them into the camera viewport? How hard is that to do? Freakin' awesome math skills needed?
5) Does openGL ES support some kind of shader tree model with gradients and effects that can be applied to the model or material?
Would be so happy if someone can point out an quick starting guide for people who know 3D, but don't know OpenGL ES. Maybe someone already made a great tutorial on this topic?
How about Using 3D Models from Blender in OpenGL ES.
What I mean is, do animators work on an animation in say Flash (or some other kind
of key frame animation program) and then export it to the iphone somehow?
For example, say I am an animator and I want to create a person waving for an iphone
game. What type of external program would I use and then what libraries on the iphone
sdk would I use to load them in?
I think it all depends on how in depth you want to get. Making a 2D game is a broad statement. For example, to make what you ask. You would just make a series of PNG images for a cell based animation of the wave. wave1.png, wave2.png, waveN.png...
Then load the PNG images in and then play them in sequence. You can do this with UIImageView, Core Animations classes, or manually your self with UIImages and UIViews.
There a lot of great game engines you can check out too. Here is a link for an example of what is available. Game Engines
For the best performance, most companies/developers use OpenGL to do both 2D and 3D style games. You can utilize a lot of tricks for the textures used in your games.
The iPhone natively supports key frame animation with the CAKeyframeAnimation class.
I think the most popular framework for 2D games is Cocos2D: http://cocos2d.org/
