Anyone can point out a documentation or a detailed discussion using @class.
I’ve been using this but haven’t really fully understood it.
I want to learn more about it and fully understand it.
Thank you in advance.
@classis used to declare a class. Essentially telling the compiler: “Hey, there is a class with this name somewhere in the source code. The definition will come later, but let me use its name as a pointer type for now.”See also:

Note: As pointed out by Richard J. Ross III, the
@classkeyword allows for circular references (when two classes both depend on each-other) without breaking the build.
