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.
