How to Export Dae Files for Use in Scene Kit Without Seeing "Untitled-Animations"

SceneKit DAE animation not appearing in attributes

The SceneKit editor in Xcode does not display the root node in the scene graph view, and it might be the one that holds the animation.

You should be able to retrieve the root node's animation programmatically.

How to import complex .dae model to SceneKit?

It's obvious that you must export complex models from 3D packages divided into smaller parts. And, of course, you do not necessarily need to export all your 3D models separately (per one model basis). In any case, a preparation of all your 3D models for using in Game Engine is extremely time consuming process. There's no one button solution.

Complex scenes like city could be logically divided to groups of static objects: skyscrapers, posts, asphalt, houses, benches, etc. But animated objects, like people, trees or cars, must be exported from Blender and imported into SceneKit separately.

Remember, all corresponding textures for these 3D objects (whether it's a single object or a group of objects) must be saved as UV-mapped square jpeg or png files (like 512x512 or 1024x1024 pix). And do not forget about low-poly collision meshes for dynamics.

Look at WWDC 2015 SceneKit session. You'll see how to build 3D scene in Xcode's Scene Editor.

To accomplish your goal you need to export smaller parts (logically divided, as I mentioned earlier) of your 3D scene from Blender, import all the parts into SceneKit's (ARKit) project and then combine them all through Swift code. Also, many 3D packages can export multiple animations as a single animation with, so called, sub-animations. In this SO post you can find how to handle it.

SceneKit – Animation with DAE file format

It was my mistake, I need to save rig in initial model. Previously I saved rig only for animation. Now animation works fine.

Common export format between OpenGL and scene kit

SCNRenderer will allow you to use your SceneKit model and code in your GL ES project.

The Model I/O framework may be of use to you as well. An MDLAsset can be created from a SceneKit scene, saved to file, and then loaded in an Open GL project. See MDLAsset(SCNScene: scene).
