The 4th dimension is not time. I've been told a countless number of times as a child that the 4th dimension is time. It isn't. 4th dimension is simply another axis that we cannot perceive.
Some might argue that it might have some relation to time because you could be in two places at the same time but that explanation would be a stretch.
The brain extrapolates data from both eyes to construct a 3D scene...in the mind! Eyes are nothing more than lens on a camera. An eye takes a 2D snapshot of the world. The brain then takes the snapshots from both eyes and tries to determine depth. But don't think that this means that you're seeing in 3D.
Seeing things in 3D would mean that you can at all moments *know* the shape of a object by staring at it. Human beings cannot do this. You can look at something and *think* you know the shape but you could never be sure of the parts that you *can't* see without going around it and taking a 2D "snapshot" of the parts of the object that you couldn't see.
The mind has to take 2D snapshots of every side of an object and reconstruct the 3D shape in the mind. But that still doesn't mean you are seeing in 3D. The part of the object that you can't see could have changed...and while your brain visualizes the object in a certain way, if the object has changed, you'd be wrong in assuming the object was the way you're visualizing it.
For example...you look at a car from all sides. You have a mental 3D visualization of this car. Without your knowledge, someone puts a huge dent on the side that you can't see of this car.
A being that could see in 3D would have immediate knowledge of this dent without having to go around the car. But as a human being, you wouldn't know this dent was on the car unless you went for another walk around the car.
As for 2D, the eyes can take in full information from 2D. Nothing is hidden. If something could be hidden from view, then it isn't really 2D.
The mind is a beautiful thing but it's limited to what the eyes can capture. Nothing's stopping someone from imagining how it would be like to view things in 3D or even in 4D. Anyone can try to work the shape of an object with the mind or even imagine physical space shared by another dimension (superimposed physical spaces)...it doesn't mean that we can see in 3D or 4D.
For all we know, the world does not exist until we look at it.
Nonsense. Some believe a 4th spacial dimension exists, others disagree and believe the 4th dimension is time. In either case, it is fair to consider time a dimension and since the 4th potential spacial dimension has yet to be known, time is the 4th known dimension.
We have theories suggesting more than one more. But this doesn't preclude the fact that we only know of three spatial dimensions and time.
So you sir are wrong, even if there is another spatial dimension for two reasons: (a) it's an argument of semantics counter to the norm and (b) following a, time would remain a recognized dimension even with another spatial dimension.
Why would time be the 4th dimension? Time has nothing to do with dimensions.

But, okay, I'm wrong.
It has to do with the laws of relativity. Time is not as disconnected from space as it appears under Newtonian physics. The problem is that in normal life, we wouldn't know that, we know that because of the extremes in physics, not what we see in everyday life.
Apple also has a history of patenting anything and everything it can, so a patent like this has little to no relevance on future OS designs. We'll just have to wait 'n' see!
