You Deserve Nice Things
summary
Argues that small, well-scoped extensions change code: containsString added in iOS 8 is cited as a useful retrofit; shows concrete helpers like a pairs sequence built from zip+dropFirst, a typed .sum and .average lifted into Swift 3, a countWhere that avoids allocating an intermediate array, and a reverse that yields a ReverseRandomAccessCollection instead of copying. Demonstrates operator overload for Int×CGFloat, a gestureRecognizer.cancel implemented by toggling isEnabled, and notes a personal gist library that saw little adoption.
