Is OC important work also done by the compiler ?, Oc compiler completed

 

NO, the important work of OC is done by the "runtime component" instead of the compiler. In fact, all data structures and functions required to use the object-oriented feature of OC are in runtime components.

For example:

The runtime component contains all memory management methods.

 

So what is ''runtime component?

The runtime component is essentially a "dynamic libary" linked to the Code Compiled by the developer. Its code can bond all programs compiled by the developer.

The advantage of this is that you only need to update the runtime components to improve the application performance. If you want to improve performance, you need to recompile the application code.
