| Summary |
Annotation Swift greatly simplifies the process of developing applications for Apple devices. This course helps you develop client-side and server-side applications, as well as web services using Swift. Key FeaturesTeaches you how to correctly structure and architect software using SwiftUses real-world examples to connect the theory to a professional settingImparts expertise in the core Swift standard libraryBook DescriptionTake your first foray into programming for Apple devices with Swift. Swift is fundamentally different from Objective-C, as it is a protocol-oriented language. While you can still write normal object-oriented code in Swift, it requires a new way of thinking to take advantage of its powerful features and a solid understanding of the basics to become productive. What you will learnExplore the fundamental Swift programming concepts, language structure, and the Swift programming syntaxLearn how Swift compares to other computer languages and how to transform your thinking to leverage new concepts such as optionals and protocolsMaster how to use key language elements, such as strings and collectionsGrasp how Swift supports modern application development using advanced features, such as built-in Unicode support and higher-order functionsWho this book is forIf you are seeking fundamental Swift programming skills, in preparation for learning to develop native applications for iOS or macOS, this book is the best for you. You don't need to have any prior Swift knowledge; however, object-oriented programming experience is desired |
