Answer 2

About the entry threshold: nothing specific, better understanding of OOP, experience in C / C ++ will be a small plus, and everything else will be obtained in the process of learning SDK. It is clear that any SDK has "favorite patterns", they can also be studied already in the process.
About the junior: There is something to argue about, and it is obvious that there are no strict limits, personally, I think that it is enough just to read one thick book "about everything" on iOS development and try everything from there.
From the fundamental:
1. pattern delegate, KVO, notification, singleton, be able to use blocks (it is not even necessary to write them yourself)
2. network interaction
3. Working with UITableView
4. Be able to create working buttons both from the interface and from the code.
5. Be able to transfer calculations to another thread in any way.
But I would still google on the topic of what is needed for a junior and make up my own point of view if I were you.
