I did not give this book 5 stars simply because I wish it had challenges at the end of each chapter. In this book the author demonstrated several ways to code Swift, the traditional way and a more common simpler way. Chapter 6, Putting It All Together, walks you through the integration of all the different parts developed in previous chapters and shows the use of functional tests. I have about three other Swift programming books, but this is certainly my most favorite. By writing tests first test-driven development , the developer focuses on the problem. The intro to Swift and Xcode is then followed by what amounts to almost or even more than half of the book spent laboriously building a storyboard. Many projects have already surpassed desktop applications in their complexity.
I like the author style of writing he kind of take you by the hand and walk you through the basics and intricacies of the Swift language. The entire storyboard is built before a single line of code is written to relate anything we are doing in the storyboard with associated code. Even an intermediate Swift programmer or someone coming from another language can benefit from what information is provided in this book. If you really want to learn the basics of Swift this is the book to buy. . Chapter 8, Where to Go from Here, wraps up and shows you the possible next steps to improve your acquired testing skills.
I do not agree with the earlier review--I thought that this book was well written and surely worth the price. Chapter 7, Code Coverage, shows you how to measure the code coverage of your tests using Xcode. You may come away from this book feeling like you have built an app, but having learned how to build your own app? I prefer to build an app from beginning to end. I really enjoyed doing the challenges, but the book did not provide enough challenges. Most other subject related books that I have read start you off with a partially initiated app to build. Another alarm bell was ringing due to the shockingly poor presentation of the content in the book, but I never-the-less persevered. With further guidance on beta testing with TestFlight, you'll quickly learn everything you need to get your project on the App Store! One important strategy to manage this complexity is through the use of unit tests.
By writing tests, a developer can point out the intention of the code and provide a safety net against the introduction of bugs. As a result, the code is clearer, and the developer gains more confidence that the code actually works. By the time you get to writing code to drive your table views you will likely have forgotten how you built those table views. I am very please with this purchase. And again, the building of the storyboard is by rote, relying on detailed but at times frustratingly vague or poorly written instructions without explaining why certain values are changed or what the effect is.
This way, they are forced to think about the domain and rephrase a feature request using their own understanding by writing the test. You will experience different strategies for writing tests for models, view controller, and networking code. Chapter 4, A Test-Driven View Controller, shows you how to write tests for a view controller, and describes how to use fake objects to isolate micro features for the test. So take advantage of this developer-friendly guide and start building applications that may just take the App Store by storm! You do not need any knowledge of Swift or any prior programming experience. Chapter 5, Testing Network Code, teaches you to test network code using stubs to fake a server component before it is developed. In this book I also learn how to intersect and join sets I don't recall reading that elsewhere. Some of the things you'll be introduced to are: Xcode, playground, integers, optionals, functions, collections, Core Data, and you'll build a complete useful app from scratch.
