Because few developers learn Smalltalk, most need to adjust their thinking to get the most. I’m not going to give a computer science history lesson here, but it’s important to understand that Objective-C is not Java and it’s not C++. Common Cocoa patterns include protocols, dynamic typing, customization through delegation, message passing, and shared object ownership. Cocoa has very different patterns, and this is what sometimes gives new developers trouble. When Apple brought NeXTSTEP to the Mac, it renamed it Cocoa, although the NS prefix remains to this day. It was written in Objective-C and implemented many of Smalltalk’s patterns. NeXT developed a framework called NeXTSTEP. Objective-C and Cocoa come from the Smalltalk fork. Its patterns include generic programming, static typing, customization through subclassing, method calling, and strong object ownership.

Today, most developers are trained in this branch of Simula.

Microsoft wrote Java.NET and called it C#.

From C++ sprung Java, which tried to make things easier. In the beginning there was Simula, and Simula had two children: C++ from Bell Labs and Smalltalk from Xerox PARC. None of these languages really prepare you for how to think in Objective-C. You probably have a background in other object-oriented languages like Java, C++, or C#. If you’re like most iOS developers, Objective-C is not your first language. Chapter 4: Hold On Loosely: Cocoa Design Patterns
