Here's a thought
Why not send the updates to Apple first and release them to the other platforms when the Apple update is on line.
You say that Android and other systems update within days
This would mean that we were all on the same update within a couple of days rather than Apple users having to suffer disadvantages like sinking into the ground and being unable to get into tanks.

I always send it to apple first. But the problem is that do you think it is fair that everybody in the game has to wait for Apple ALWAYS?

I don't think it's fair that if I bought an Android or a PC, I have to wait for Apple to push the publish button, which by the way, on one occasion took 3 months! On average it is 10 days. If I bought other brand is exactly to avoid having the issues that the competing brand has.

So no, not everybody is on the new version within days if I did that. It would be within weeks. As of right now, I released 2 updates to all platforms that Apple still does not have even began to review (and I sent it to them first because I know they are slow)
