It all depends on whether Apple makes ARKit a priority, though. Apple has advertised SpriteKit on various occasions, then mostly broke it in iOS 9.0/9.1 [1], [2]. Game Center went down once a single game (Letterpress) started using it as designed [3]. What will you do if ARKit breaks in iOS 12.0? If you use an third-party lib, at least you can roll back to an earlier version, or even fix the bug yourself if it is open source. I would stay as far away from Apple as possible when it comes to gamedev tools.
