I'm thinking Apple might officially release a ML "search" at some point. I can imagine a life where they sell a variety of models (price determined by model complexity/size)... not sure if that's better or worse.
They leave it to the open source community and only due to lots of pressure, did they finally released something like "Android Architecture Components".
Tango as other mentioned is not actually there.
Stuff like CoreML, MetalKit, Model I/O, GameKit, SceneKit, SpriteKit, Image I/O,... just doesn't exist at the same level as Apple.
Well, some of them do exist, but as open source projects without any support from Google.
Google licensed one of the AR patented from Flyby Media which Apple has acquired and its patent portfolio, we see why Apple could developed it faster.
