A Deeper Deep dive into Swift Literal
summary
Deep dive that traces Swift literals from source through SIL and LLVM IR snippets into runtime, showing actual compiler output and the GitHub compiler code used to generate it. Explains how literals become literal objects (Builtin.Int64 etc.), how those objects are passed to initializers and wrapped by types like CGFloat, and why color/image/file literals land as editable resources in Xcode. Includes concrete SIL examples, mentions Intrinsic/ExpressibleBy protocols, and links to slides and repo for the demos.
