Build-a-Binary
summary
Explains how Xcode turns source into an app by walking the actual pipeline: compilation, Swift Intermediate Language (SIL) step unique to Swift, object files, and the linker that produces the runnable binary, plus where Objective‑C and Swift converge. Describes developer‑infra work at Spotify that generates Xcode projects with Basil, the real tools invoked (clang/Swift compiler, archiver, linker), and clarifies this is an explainer not a live build‑a‑binary demo.
