A solid reference for writing Swift that doesn't look like translated Objective-C. Covers the fundamentals: naming conventions (UpperCamelCase for types, lowerCamelCase for everything else), the golden path pattern with guard statements instead of nested ifs, and when to omit self. The common mistakes section is the most useful part, calling out real issues like overusing abbreviations beyond URL/ID/UUID and slapping Manager or Handler on everything. It's opinionated in the right ways, like preferring private over fileprivate and always using trailing closures for single closure parameters. Keep this handy when reviewing code or onboarding developers who need to write idiomatic Swift instead of whatever they learned from random tutorials.
