Looks like Objective-C is being replaced by Swift.  However, I am learning the language for work.  I have looked at it over the years, but never really programmed in.  I have always liked the language.  I believe that it was far superior to C++ when it came out; however, just because it's better doesn't mean it will become more popular, as is evidenced by the popularity of C++.

Locations for learning the language.  I have been reading the book "Programming in Objective-C, Sixth Edition", by Stephen G. Kochan, 2014.



Nice book and seems well written.  A little old for Xcode and iOS, but was the most current general book that I could find.

Also looking at "Programming with Objective-C" in the Mac Developer Library.  Last updated 2014.

There is also a "Object-Oriented Programming with Objective-C" in the Mac Dev Library, 2010.

Here is the links I found in Mac Developer Library;

• Finding and Fixing Category Method Name Clashes, 2016
• Adapting Modern Objective-C, 2014
• Programming with Objective-C, 2014
• Objective-C Runtime Reference, 2013
• Objective-C Feature Availability Index, 2013
• Improved logging in Objective-C, 2011
• Blocks Programming Topics, 2011
• Object-Oriented Programming with Objective-C, 2010
• Objective-C Runtime Programming Guide, 2009
• Objective-C Release Notes, 2007
• Variable arguments in Objective-C methods, 2005

Let the programming beginning!
