Emerging Best Practices
summary
Shows concrete Swift 2 techniques and why they matter: demonstrates guard/defer/enum associated values usage, explains dependency injection by swapping a network controller for a protocol-backed stub in unit tests, and gives a working pattern for injectible NSUserDefaults via default parameters. Explains currying for reusable filters, contrasts refactor vs rewrite (changing tests means rewrite), and argues unit tests improve API design. Watch if you want runnable patterns to make Swift code testable and easier to change.
