This event has ended.

What you’ll learn and how you can apply it

By the end of this live, online course, you’ll understand:

  • How and why to implement common design patterns for your code and your app UX, using Swift 4 for iOS 11 apps.
  • You’ll be ready to dive further into Swift on your own, understanding what makes a Swift app a Swift app, and you’ll know how to ‘think in Swift’ for common algorithms.

And you’ll be able to:

  • Use advanced algorithms in Swift.
  • Use common visual styles and design principles, through Swift, in their iOS apps.
  • Optimize their apps for speed and efficiency.

This live event is for you because…

  • Swift developers wanting to expand their knowledge
  • mobile developers who want to level-up to the latest technology
  • Objective-C developers now moving to work in Swift
  • anyone who wants to learn how to build iOS, tvOS, or watchOS apps
  • these skills generally apply to macOS apps as well
  • If you are involved in writing apps and services to related to Apple Watch, Apple TV, iPhones, iPads, or Macs, you need to become familiar with Swift.

Prerequisites

This course is intended for programmers who have some experience with Swift, or are familiar/experienced in any modern language, e.g., a year or more working in Python, Java, C++, C#, etc.

  • Familiarity with operating macOS as a user
  • Basic knowledge of Swift (preferred) or any other modern language
  • Access to a Mac with Xcode 9 (beta) installed
  • An iOS device is not needed for this course

Recommended preparation:

Learning Swift, 2nd Edition (book)

iOS Swift Game Development Cookbook, 2nd Edition (book)
