{ "item_title" : "Swift 6 & SwiftUI Engineering Blueprint", "item_author" : [" Trudy M. Eskridge "], "item_description" : "Ever opened a SwiftUI project that worked fine on your machine, shipped it, and then watched it fall apart the moment real users and real data got involved? You're not alone, and it's not because you're a bad engineer. It's because writing code that compiles is a completely different skill from designing an application that holds up under pressure, scales with a team, and doesn't quietly rot six months after launch.That's the gap this book is built to close.If you've already got the basics down - you know your way around structs, optionals, and a SwiftUI view or two - but you're tired of tutorials that stop right where the real questions start, this is for you. What actually happens when strict concurrency checking turns your warnings into hard errors? How do you structure state so five different views don't end up with five different opinions about what's true? When do you reach for a dedicated view model, and when is that just extra ceremony nobody asked for? This book answers those questions directly, with real code, real trade-offs, and zero hand-waving.Here's what you'll actually get out of it: A clear, working mental model for the newer concurrency rules - actors, isolation, and the Sendable requirement - explained in plain language, not compiler-speak. You'll understand not just how to make the errors go away, but why they exist in the first place, which is the difference between silencing a warning and actually fixing the problem underneath it.A grounded look at state management that doesn't pretend there's one correct answer. You'll see when a lightweight, model-first approach is genuinely enough, and when a more structured pattern earns its keep - including an honest walkthrough of a popular architecture library, its real strengths, and where it's simply more than a given screen needs.A full breakdown of how navigation, data flow, and persistence should actually talk to each other, so a screen three levels deep in your navigation stack doesn't end up guessing what state it's supposed to reflect.Practical guidance on testing that doesn't feel like homework - how to structure your code so tests are actually easy to write, what's worth testing versus what's a waste of your afternoon, and how to know when your coverage is genuinely protecting you rather than just padding a percentage.A performance and profiling section that treats your intuition as a starting hypothesis, not a conclusion - because the slow part of your app is almost never the part you assumed.And a full capstone project that ties every one of these decisions together in one connected build, the way a real project actually unfolds, not as isolated examples that never have to coexist.This isn't a reference manual you skim once and shelve. It's written the way a thoughtful senior colleague would walk you through their own reasoning - showing you the messy first attempt, explaining what was wrong with it, and then building the version that actually holds up. Every chapter assumes you want to understand the why, not just copy the what.So who is this actually for? If you're a working developer who's shipped an app or two and wants to stop second-guessing your architectural instincts, this is your book. If you're leading a small team and need a shared reference everyone can point to during a design discussion, this is your book. And if you're migrating an existing project into the newer language and concurrency rules and dreading the process, this book was written specifically with you in mind - it doesn't just explain the new features, it gives you an actual, staged plan for getting there without breaking everything at once.You've read enough tutorials. It's time to build like it's your job - because for most of you reading this, it already is.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/819/284/9798192848265_b.jpg", "price_data" : { "retail_price" : "19.99", "online_price" : "19.99", "our_price" : "19.99", "club_price" : "19.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
