DAE fails to keep morph animation when imported to scenekit/xcode

Exported animated file from 3DS Max 2017 which has both bone animation (for limbs) and morph animation (for mouth).
Everything, but the morph animation comes into scenekit. It seems the target array is empty??

Start with the supplied COLLADA controller XML, where the morph target and weight arrays have count="0", and trace how morph controllers and animations are imported. Reproduce with the 3DS Max 2017 asset if available; done when both bone and morph animations are preserved for SceneKit/Xcode.
