Modern Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Even better, you don’t even need to type semi-colons. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases. Declare new types with modern, straightforward syntax. Add functionality to existing types using extensions, and cut down on boilerplate with custom string interpolations. extension Player: Codable, Equatable {} import Foundation let encoder = JSONEncoder() try encoder.encode(player) print(player) Perform powerful custom transformations using streamlined closures. Designed for Safety Fast and Powerful Open Source

The Swift Programming Language: A Swift Tour Tradition suggests that the first program in a new language should print the words “Hello, world” on the screen. In Swift, this can be done in a single line: If you have written code in C or Objective-C, this syntax looks familiar to you—in Swift, this line of code is a complete program. You don’t need to import a separate library for functionality like input/output or string handling. Code written at global scope is used as the entry point for the program, so you don’t need a main function. You also don’t need to write semicolons at the end of every statement.

Cocoa Touch - iOS Technology Overview Built on Objective-C Much of Cocoa Touch is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employs a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa Touch applications. As your application runs, the Objective-C runtime instantiates objects based on executing logic – not just in ways defined during compilation.

iOS 8 for Developers Download and Install iOS 8 SDK and Xcode 6 Get your apps ready for iOS 8 by downloading and building with the iOS 8 SDK and Xcode 6.0.1. With Xcode 6 and iOS 8, Swift is now final, and you can submit your iOS apps written with Swift to the App Store. Wants Mandatory Computer Science Classes in Schools To music artist, technology can change the world. On Tuesday,, the former Black Eyed Peas singer whose legal name is William Adams, dropped by the Apple Store in San Francisco’s Union Square for a screening of the music video for a new version of the group’s 2003 hit Where Is the Love? He was joined by Apple retail chief Angela Ahrendts, and discussed why the proceeds from the song would go toward education programs and initiatives through Adams’ foundation. Specifically, Adams highlighted the importance of making computer science classes available more broadly in schools, especially in disadvantaged neighborhoods. “What success would look like… In every inner city, third period—’where are you going?,’ I’m going to iOS class,” he told Ahrendts when asked about the ideal outcome of his efforts to improve education.

Getting Started - Vapor Docs JWT (vapor/jwt) is a package for parsing and serializing JSON Web Tokens supporting both HMAC and RSA signing. JWTs are often used for implementing decentralized authentication and authorization. Since all of the authenticated user's information can be embedded within a JWT, there is no need to query a central authentication server with each request to your service. Unlike standard bearer tokens that must be looked up in a centralized database, JWTs contain cryptographic signatures that can be used to independently verify their authenticity. If implemented correctly, JWTs can be a powerful tool for making your application horizontally scalable.

Android Developer SDK Before installing Android Studio or the standalone SDK tools, you must agree to the following terms and conditions. This is the Android Software Development Kit License Agreement 1. Introduction 1.1 The Android Software Development Kit (referred to in this License Agreement as the "SDK" and specifically including the Android system files, packaged APIs, and Google APIs add-ons) is licensed to you subject to the terms of this License Agreement. What’s the Difference Between Coding and Computational Thinking? In my last EdSurge article, “Computer Science Goes Beyond Coding,” I wrote about the difference between coding and computer science, to help us understand what we mean by phrases like “Teach kids to code” and “Computer science for all.” In that article and in many other articles, there is another term that appears often: “Computational thinking.” Well, what is Computational Thinking (CT), and how does it differ from Coding and Computer Science—especially when it comes to classroom practice and instruction? What is Computational Thinking (CT)? My short definition: CT is a strategy that uses many of the powerful ideas in computer science to solve problems.
