What is OBJC?
Objective-C is the primary programming language you use when writing software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime.
What does @() do OBJC?
In Objective-C, any character , numeric or boolean literal prefixed with the ‘@’ character will evaluate to a pointer to an NSNumber object (In this case), initialized with that value. C’s type suffixes may be used to control the size of numeric literals.
Why is Objective-C so different?
Objective-C uses the runtime code compilation Objective-C isn’t a fast language. The main reason is that it uses the runtime code compilation, rather than the compile time. This means that when the Objective-C object calls for another object in the code, there is an extra level of indirection involved.
Is C++ better than Objective-C?
hpp etc. C++ influenced many programming languages like Java, C#. It has been the third most used programming language after Java and C….C++ vs Objective C Comparison Table.

Does Objective-C have reflection?
Yes, Objective-C has reflection (and abstract classes). Whether that reflection fits your needs or not is a different question. Reflection in Objective-C is surprisingly flexible for a C derived language. You can ask a class what methods it implements or you can modify and/or add methods to existing classes.
Where can I find the runtime library in Objective-C?
Objective-C runtime library support functions are implemented in the shared library found at /usr/lib/libobjc.A.dylib. You typically don’t need to use the Objective-C runtime library directly when programming in Objective-C.
What is objc_object data type?
An opaque type that represents an Objective-C declared property. Defines an Objective-C method. Defines a property attribute. These are the data types that represent objects, classes, and superclasses. objc_object pointer to an instance of a class.
Is Objective-C an object oriented language?
While Objective-C is a fully dynamic, reflective, object oriented language, that doesn’t mean that such patterns are encouraged or typically used. In Objective C, how to find out the return type of a method via reflection?
