Ios app problem at the beginning of the journey?

Question

iOS

Greetings!
I want to go straight to the question, I decided that I want to become an ios developer, but I can’t understand one thing, there are different versions of swift and xcode and I found an initial course, but let’s say they use xcode 9 and swtift I don’t remember much but not 5, this is very critical or you can first learn the old material, and then move on to the new one, it’s just that I find information, but someone says that this book is already old, etc., and I wanted to know if it’s worth starting to study ios dew from old versions of jap

As you wrote - at the beginning of the journey it is absolutely not important, the main thing is not to be very ancient) Absorb any information like a sponge and put it on the shelves, what's for. At a minimum, xcode will tell you that "this is better replaced with this" or "this is deprecated".
