On Progressive Disclosure in Swift
summary
Swift deliberately layers complexity so beginners use strings, arrays and optionals while advanced users opt into generics, concurrency and ownership. It shows why property wrappers felt like magic and how macros with inline expansion fix that by exposing generated code in the IDE. Compiler diagnostics link to docs (docs.swift.org) for guided error recovery. New features include typed throws to avoid heap allocations in embedded contexts and non-copyable types with optional retrofitting; rethrows semantics remain a compatibility dilemma.
