'Reality Composer – How to rotate an object forever?

I'm developing an AR app for iOS with Reality Composer.

In my scene I have a simple sphere that i want it to rotate forever without restarting the animation every time.

Currently I set up a rotation behavior for the Sphere as soon as the scene appears. The rotation lasts 20 seconds and I clicked to the loop button in order to make it loop.

enter image description here

Unlucky this won't give me the expected behavior: The animation lasts for 20 second and then it restarts but with a very ugly "lag".

Is there a way to make the rotation forever? In SceneKit it was something like repeatForever.

For perpetual rotation in Reality Composer app you need to implement a Spin behaviour to a model. At first apply Custom Behaviour, then apply a Scene Start Trigger and at last Action Sequence Spin with default properties.

The only drawback is a "twitching" animation.

P.S.

However, there's one interesting workaround.
