Ferrocene, an open‑source Rust compiler toolchain, has achieved IEC 61508 SIL 2 certification for its core library, highlighting Rust’s growing role in memory‑safe, safety‑critical embedded devices and outlining the implications of SIL levels, certification bodies, and real‑world industrial use cases.
This article dives deep into Swift's Array implementation, explaining how the language allocates memory, the role of SIL and internal structs like _Array, _ArrayBody, and _ContiguousArrayStorage, and how copy‑on‑write ensures efficient mutation handling, all illustrated with real code snippets and debugger output.
This article provides a comprehensive, step‑by‑step exploration of Swift closures on iOS, covering their definition, different forms, practical usage scenarios, the compiler’s SIL generation process, capture list behavior, memory storage details, and best practices for avoiding reference cycles.
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.
This article provides a comprehensive, low‑level exploration of Swift's Array type, detailing its memory layout, the SIL generation process, buffer allocation, internal structures such as _ArrayBuffer and _ContiguousArrayStorage, and the copy‑on‑write behavior that governs mutation and reference counting.
This article delves into the inner workings of Swift enums—covering their compilation to SIL, memory representation, use of MemoryLayout for size and alignment, techniques for retrieving variable addresses, the role of raw values and associated values, and how default protocols like Equatable and Hashable are automatically provided.
This article examines a real iOS project case where a UITableView delegate method does not fire, explores Swift Intermediate Language (SIL) and thunk functions, explains the role of @objc and dynamic dispatch, and demonstrates how generic base classes affect Objective‑C visibility of delegate methods.
This article explains how Swift leverages LLVM's three‑stage compiler architecture and the Swift Intermediate Language (SIL) to implement protocol extensions, detailing the generation and analysis of SIL code, VTables, Witness Tables, and function calls to reveal the language's underlying compilation process.
