Understanding Swift SIL and Method Dispatch Mechanisms

Swift inserts the high‑level SIL intermediate representation between source code and LLVM, exposing type declarations, method blocks, and virtual tables, while supporting three dispatch strategies—direct for value types and final methods, VTable for regular class methods, and Objective‑C message dispatch for @objc dynamic methods—crucial for debugging mixed Swift/Objective‑C and protocol‑extension behavior.

Understanding Swift Object Creation, Method Dispatch, and Memory Layout – A C‑Style Pseudocode Exploration

This article explains how Swift objects are created and destroyed, how method calls are implemented compared with Objective‑C, the memory layout of Swift classes, the role of virtual tables, the impact of compiler optimizations, and the feasibility of runtime method replacement, illustrated with extensive C‑style pseudocode examples.
