just install Swift Playgrounds and see first if that is something you actually feel like doing.
While not fully features and comes with caveats, it is already a stepping stone to experiment.
Others will tell you to learn Vulkan and use MoltenVK for the iPad.
Now, I would rather advise to pick a middleware like Ogre 3D, Unity, Unreal, specially if you are getting into the field.
Then you can consider if it is worthwhile the monetary investment to carry on.
