To get the most out of this book

Some working knowledge of the Swift programming language would be required. You could be a beginner in terms of Swift programming, a seasoned iOS or macOS developer, or a software developer who wants to work on practical Swift applications while learning the language itself. By the end of the book, you will be able to successfully create your own web applications and web services by leveraging the powerful ecosystem of Swift.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The decode() function returns a future for HTTPStatus".

A block of code is set as follows:

router.post("new") { req -> Future<HTTPStatus> in
    return req.content.decode(Entry.self).map { entry in
        print("Appended a new entry: \(entry)")
        return HTTPStatus.ok
    }
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

import Foundation

struct Entry: Codable {
    
    var id: String
    var title: String?
    var content: String?
    
    init(id: String, title: String? = nil, content: String? = nil) {
        self.id = id
        self.title = title
        self.content = content
    }
}

Any command-line input or output is written as follows:

 $ vapor build
 $ vapor run

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Navigate down the list and click on the Swift Web App with Kitura icon".
