I've asked this question before, but it was not clear enough, so I'll explain again.
I'm learning Objective-C with a book. However, this book is old, and in it, the author of the book uses version 4.3 of Xcode. Right from the start, it teaches you how to create a new project in Xcode (very easy).
When I followed these steps in Xcode 7.1.1, in the "Type / Type" area, I did not find the "Foundation" option that it selects, there is no "Foundation" type, only Objective-C, Swift, C and C ++. Which of these languages is Foundation? Was objective-c? What's the difference?
Thank you in advance.
