First of all, what is Swift?
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. (Wikipedia)
It’s an easy programming language to learn, which is why many students, entry-level developers, and Mac and iOS developers are focused on Swift. In addition, Apple open sourced Swift, making it available for developing on other platforms, not just those designed by Apple.
Let’s take a look into pros and cons of Swift language (acc. to altexsoft.com)
- Rapid development process
A clean and expressive language with a simplified syntax and grammar, Swift is easier to read and write. Automatic Reference Counting (ARC) does all the work tracking and managing the app’s memory usage, so developers don’t need to spend time and effort doing that manually. Accordingly, it usually takes less time to build iOS apps with Swift.
- Easier to scale the product and the team
Your products are future-proof and can be extended with new features as needed.
- Improved safety and performance
- Interoperability with Objective-C
As Jordan Morgan, iOS developer at Buffer, wrote in his Medium post, “[…] swift is the new toy and marked as the future. Objective-C is showing its age and will, eventually, be much less prevalent. But in the here and the now, the two must learn to coexist peacefully.”
Swift language is perfectly compatible with Objective-C and can be used interchangeably within the same project.
- Full stack potential and cross-device support
Server-side Swift integrates with most of the popular backend technologies. Using Swift on both backend and frontend of your app allows for extensive code sharing and reuse, speeding up the development process and reducing development efforts.
- Swift is still quite young
Swift is still too young and it has many issues that need to be addressed and “growing pains” to experience. Three years is too little time for any language to mature.
- Swift is considered a “moving target”
Swift is often considered to be unstable due to the major changes that are introduced with every new release. One of the key problems is the lack of backward compatibility with the older language versions. Consequently, developers are forced to completely rewrite their projects if they want to switch to the latest Swift version.
That was a little introduction to the language for those who are not familiar with it. So now let’s pass over to some of the best Swift books in 2017.
iOS 10 Programming Fundamentals with Swift: Swift, Xcode, and Cocoa Basics (eBook — $29.49, paperback — $41.61)
Move into iOS development by getting a firm grasp of its fundamentals, including the Xcode IDE, the Cocoa Touch framework, and Swift 3 — the latest version of Apple’s acclaimed programming language. With this thoroughly updated guide, you’ll learn Swift’s object-oriented concepts, understand how to use Apple’s development tools, and discover how Cocoa provides the underlying functionality iOS apps need to have.
- Explore Swift’s object-oriented concepts: variables and functions, scopes and namespaces, object types and instances
- Become familiar with built-in Swift types such as numbers, strings, ranges, tuples, Optionals, arrays, dictionaries, and sets
- Learn how to declare, instantiate, and customize Swift object types: enums, structs, and classes
- Discover powerful Swift features such as protocols and generics
- Catch up on Swift 3 innovations: revised APIs, new Foundation bridged types, and more
- Tour the lifecycle of an Xcode project from inception to App Store — including Xcode’s new automatic code signing and debugging features
- Construct app interfaces with the nib editor, Interface Builder
- Understand Cocoa’s event-driven model and its major design patterns and features
- Find out how Swift communicates with Cocoa’s C and Objective-C APIs
Learning Swift: Building Apps for macOS, iOS, and Beyond (eBook — $29.49, paperback — $30.82)
Get valuable hands-on experience with Swift 3, the latest version of Apple’s programming language. With this practical guide, skilled programmers with little or no knowledge of Apple development will learn how to code with Swift 3 by developing three complete, tightly linked versions of the Notes application for the OS X, iOS, and watchOS platforms.
In the process, you’ll learn Swift’s fundamentals, including its syntax and features, along with the basics of the Cocoa, CocoaTouch, and WatchKit frameworks. This book teaches you how to use common design patterns for Swift, how to structure an application for Apple’s platforms, and how to submit working apps to the App Store.
Divided into four distinct parts, this book includes:
- Swift 2 basics: Learn Swift’s basic building blocks and features for object-oriented development
- OS X app development: Set up the document model, build out features, and sync data with iCloud
- iOS app development: Use multimedia, contacts, location, notifications, and iCloud files to build a fully featured iOS Notes app
- Advanced app extensions: Build an Apple Watch app, and learn how to debug, monitor, and test all three of your Swift apps
iOS 10 in Swift 3 (eBook — $31.85, paperback — $47.92)
iOS 10 in Swift 3 will take you from absolute beginner to functional iOS developer learning the concepts, techniques, and tools needed to build professional iOS applications using Xcode 8, iOS 10, and Swift 3. After completing this book, you will have the skills and confidence you need to to build and design your own iOS apps and apply for jr. iOS development jobs. This book is patterned after the widely popular & fun hands-on training that Devslopes has provided to over 100,000 students worldwide. Unlike other books and training, this book teaches you through real-world app development — projects you would actually build in a job or startup, including learning UI/UX & app design with Sketch. You’ll get different insights from each member of Team Devslopes that will help you become a lifelong programmer and amazing iOS app designer & developer.
