Customizing Xcode for yourself and fixing problems for a MacOS X newbie?

Question

Apple Xcode

A MacBook Air appeared in my life and downloaded the new OS of Captain and after Linux is still familiar, but there are still incomprehensible moments, but I would like to learn how to write applications for iOS and downloaded XCode, but there are many jambs with the Swift language (for example, I write println , it says that it replaces with print, but when compiled, the text is always \n after). I myself learn from the stories of people and there are many inconsistencies in the codes.
If someone can tell you how a teapot can learn how to use XCode or debug it for yourself, please give advice, just ask without your pretentious moments, but express a simple normal opinion

Answer 1

The best source of knowledge is the documentation from Apple.
The almost classic ray wenderlich is perfect for a start.
Setting up xcode:
Alcatraz package manager and choose for yourself. I actively use Fuzzy Autocomplete, XVim and something with Rainbow colors.
Print & Println:
This was an update of Swift itself a long time ago, println was removed, and now this is the default behavior of print. Line feed is removed by some flag.
