Draw UML class diagram of Objective-C program

This flowchart illustrates the UML class diagram of an Objective-C program, showcasing the hierarchical and functional relationships between various classes and protocols. It highlights the classification of classes, such as Class C inheriting from Class A, and the C-B category's superclass relationship. The diagram also details operations and attributes, including operations within Class C and its implementation of protocol D. Additionally, it outlines the association between Class E and D, emphasizing compliance with protocol specifications. This structured representation aims to provide a clear understanding of class interactions and design patterns within Objective-C programming.
