Swift is a programming language for creating iOS, macOS, watchOS, and tvOS apps. Swift builds on the best of C and Objective-C, without the. The Swift Programming Language book. Read 44 reviews from the world's largest community for readers. Swift is a new programming language for creating iOS. Take advantage of using the same programming language for both server and client-side with this hands-on book for building web applications with Swift.
Xcode makes a big appearance in this book as the primary IDE for Swift development. The tutorials guide you through Xcode playgrounds teaching you how to understand the code you write.
But the applications are not exactly related to iOS development. So if you have no prior knowledge this book can get you moving fast with Swift as a programming language.
This title is for programmers who already know the basics of Swift and want to learn more about the functional programming methodology. Swift 3 is currently the newest version of Swift released alongside iOS This book covers more detailed topics like pattern matching and map functions like the flatMap filter.
But you will need to know the basics of Swift programming and have access to the Swift 3 dev environment. Protocol Oriented Programming with Swift Getting even more advanced we find the topic of protocol-oriented programming as it relates to Swift. This means extending and building on top of protocols like you would a class.
Protocols are generally unique to Swift and not as popular in other languages. You can find many blog posts discussing protocol-oriented programming and how it applies to Swift development.
You can build iOS apps just fine without learning these features.
The Swift Programming Language (Swift 3.0.1)
But if you ever want to get into advanced Swift development this book is a must have resource. But how do you optimize your code for better performance?
The author Gaurav Vaish teaches you how to measure performance on your device and to optimize your code for CPU load. When you learn to use the right analytics tools you can study slowdowns and bottlenecks while the app is in use. Editor area: Center area where the files are shown. Utility area: Where tools and identities of the objects can be modified.
Toolbar: Where the run button and the activity viewer are. But when you create a new project, three default folders are created: Your main application folder, the test folder and the product folder.
You can also create Groups to organise your work or use folders to keep your program environment clean. Start Programming[ edit ] Apple has a comprehensive documentation with tutorials included on their website. For starting out, here is a tutorial where basic concepts are explained along with images, examples, and concept definitions.
The tutorial can be found here. It is a good way to start, but if you continue their series of tutorials, it would take a long time and can be boring and unnecessary.
One of the most useful methods to learn a new programming language is to take a look at the examples available on any tutorial, as most of them are To-do List implementations that show how to connect Segues and return to the original View controller to display the information. Jack Watson's Series of tutorials explain Swift's features, step-by-step, for simple applications. And hopefully a much quicker read! Adding elements to your project[ edit ] Adding Libraries: For built libraries, Xcode has a 5 step procedure Adding Files: Using Xcode you can just drag the files from the Finder Window and drop the into your project folder in the Xcode Navigation Area.
The Swift Programming Language (Swift 5.0)
Configuring for development[ edit ] For programming in Xcode and running your app in the simulator, it is not necessary to have a certificate but you have to create an account anyways. But when you want to test the app in your own device, a developers certificate is needed and also you need to you install an associated provisioning profile on the device to enable the app to run.
As it is specified in the site , the iOS Developer Program allows you to install your app on up to iPad, iPhone or iPod touch devices. Configuring for deployment[ edit ] Configuring your application for deployment is one of the trickiest parts of the development process, which is why you should follow and read every step in this guide.
The first two statements shows some code in Objective-C and the other two statements shows the same code in Swift. Even for a beginner, the second example code seems less intimidating than the first.
Swift is still a rather new programming language but its popularity and adoption has been increasing faster than any other language.
It is now the most popular language to develop for Apple devices. Because it was open sourced by Apple, we are bound to see its use spread to include development for other platforms other than Apple devices.
As of now, there is already a compiler for it for Linux. Swift was released under the Apache 2. Facebook and Uber are also apparently looking to make Swift more central to their operations. A benefit of Swift is that it can serve as both a forward-facing language as well as a server-side one. Swift is still evolving and it will be interesting to see what it grows up to be and what it will be used for in the future. Since its announcement at WWDC , Apple developers have continued working on it, releasing incremental versions.
Swift 3. The major goal of this release is said to be portability, meant to make it more portable to other platforms.They also hold different talks that teach developers how to implement the newly introduced libraries and technologies.
I would recommend this book to people who This book was about, well, the Swift Programming Language.
1. Learning Swift
That said, it looks like the "Patterns" section feels like it's written by some other person. But it will teach you the absolute fundamentals of Swift as a language.
Larger structures like windows would be defined as classes, allowing them to be passed around as pointers. Lastly, if the guard statement's test fails, Swift requires the else to exit the current method or loop, ensuring leaseStart never is accessed when nil.
If You want to learn Swift, this is the bets guide out there. An example might be to add spell checker support to the base NSString class, which means all instances of NSString in the application gain spell checking.
Combined, these allow protocols to be written once and support a wide variety of instances. Protocols promise that a particular class implements a set of methods, meaning that other objects in the system can call those methods on any object supporting that protocol.
