What reasons make Direct Dispatch the most efficient call method?

Direct Dispatch is a method of calling functions where the address of the called function is known at compile time. This makes it the most efficient for several reasons:

• No additional runtime overhead: the call is direct, without searching for the function's address in virtual method tables or through dynamic dispatch.
• Compiler optimization: the compiler can apply inline replacements, reducing call overhead.
• Fast transition: the processor performs a jump to a known address, reducing call time.

In iOS, this is especially important for performance enhancement, as Direct Dispatch minimizes call overheads, which is critical for UI and animations.
