Swift: New Paradigms for iOS Development
summary
Swift shows concrete patterns for iOS: value structs alongside classes, interop with Objective‑C via bundled Swift libraries for iOS 7+, and a concise example that compresses a long tweet into 125 characters from a 140 limit using map filter reduce and a naive “bork” translator. Xcode’s Playground scratch pad demos live results, optionals force explicit unwrapping while implicit optionals remain dangerous, and 1.0 lacks a settled error‑handling convention.
