Swift: New Paradigms for iOS Development
summary
Line-by-line Swift vs Java examples, optionals, generics, tuples, enums, first-class functions and operator overloading are shown and used to build a small bank/accounts demo that uses reduce/fold; the demo yields a surprising copy-vs-reference behavior where modifying a copied account does not change the original bank holdings. The claim is that Swift’s value types (structs) and standard-library collections (copy-on-write) make models comprehensible, testable, parallel, portable and bridge with Objective‑C libraries via WWDC tooling.
