If you want to become an iOS developer, you have made an excellent choice with this book. Swift holds a significant position in the iOS industry because of the long list of features it serves. It is user-friendly, has great community support, and offers a greater extent of customization. As a result, we can observe a sharp increase in the market demand for developing Apple mobile applications, and with that, companies search for smart developers with the right skill set.
Mastering Swift introduces Apple’s excellent Swift standard library style and incorporates usage feedback across multiple Swift projects. However, it should be regarded as a living, changeable document and the basis upon which the programming language is implemented.
Before going further into the details of the Swift programming language, the book briefly explains the basic information about the language. It is a high-level language created to develop multifaceted iOS applications that cater diverse needs of different social and business domains. It is meant to develop high-end apps with multiple complexities. But since it is very close to Objective C, it is easy to code and understand. This feature makes it incredibly friendly to beginners as well. Moreover, it is equally compatible with iPhones, iPad, Apple Watch, MacBook, Apple Tv and can be applied to develop equally efficient and scalable apps for them.
Mastering Series encircles all the essential aspects of Swift and explores why this programming language is the future for iOS app development. Different from other languages, it requires fewer lines to activate any feature. This paves the way for a shorter development cycle and saves a lot of precious resources. Further, as one of the most reliable iOS programming language it supports dynamic libraries that indicate executable bits of code that you can link to an application. Because of such support, Swift apps can interoperate with the newest version of the language to make the app irreplaceable.
Swift is a language that was not designed but deliberately made open source in order to invite the community, let the product grow and mature over the years. This could possibly be the most crucial aspect of Swift. As people become more aware of its potential to be used in the server, web frameworks were more willing to support the demand. Owing to its popularity and significance, its adoption rate in Apple’s rival remains very high. Whether you are a beginner or an advanced learner, if you are planning for iOS app development through Swift, this book can help with the high-domain expertise and experienced resources.
Without a doubt, the developers that create native apps are not going to abandon Swift anytime soon. However, it sure seems like something has to evolve for it to keep growing constantly. We believe that now you must be convinced that Swift is indeed the future for iOS app developers. And if you are convinced and want to start learning the programming language right away, then this book is what you’re looking for.
