Welcome to the club!
I had to learn everything on my own with only the Internet and Apple's own help as a guide.
It took me over a year to get up to speed on the basics of Objective-C, Xcode and iOS app development.
And I have over 40 years of development experience on other platforms.
I imagine how frustrating it must be.
If you can find somebody local to help you one-on-one, you will be the exception.
The other thing you have to consider is that most people who know all the ins and outs also learned on their own and they are probably too busy writing apps to do any tutoring. ymmv.
