Advanced Programming with Swift 4 for iOS 11 and Xcode 9
Advanced Swift for better iOS apps
Join experts Paris Buttfield-Addison and Jon Manning for a look at advanced programming in Swift, used for developing iOS apps and services. This course focuses the latest versions of Swift, and teaches you what you need to know about design patterns, algorithms, and optimized apps.
Beginning with a quick primer on Swift 4 programming, we’ll move quickly to cover a collection of common design patterns used for iOS 11 development. Then we’ll explore the details of Swift and its standard library, including some of the more sophisticated language features, as well as useful algorithms, and UX/visual patterns used by top iOS applications.
We’ll use Playgrounds on macOS, in Xcode, for much of this workshop; Playgrounds are a revolutionary interactive way to work with and learn Swift. This workshop covers the newest Swift, Swift 4, due out with iOS 11 later this year, along with Xcode 9, the toolkit used for working with iOS apps.
This course is structured as a follow-along workshop. Also note that all of the course content was developed with teams in mind.
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 training course 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.
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
