You Deserve Nice Things
summary
Gives a four‑rule checklist for when to extend system classes in Swift and shows concrete, working code: add eachPair to produce adjacent element pairs instead of zipping with dropFirst, implement all/any/none to remove double negations, provide a countWhere that avoids allocating intermediate arrays, overload numeric operators to multiply Int × CGFloat, and expose lazy reversed collections and a gestureRecognizer.cancel helper — each extension compiles, runs, and measurably reduces noise or allocations.
