Unity IOS simple question

For making a IOS Unity application i MUST use the IOS or the IOS Pro right. So i need to bay it and then learn how to work with it, or is it same as the free version but with more features.
So my question would be can i learn how to do a IOS Unity apps for free, and then bay the IOS version, and how to test the IOS apps on the free version?

Its the same basically just different platform.
What you lose are terrains which are just to hefty for mobile.

But you can’t learn it for free aside of the trial.
And you must own a mac as well as be a paying iOS developer to deploy anything to de device

thx for your answer
