HealthKit provides a rich data store on iOS for tracking many types of data related to a users health. In this video, we will see how an application can write data to this store. After this video you can apply the same technique to allow users to save data from your application into HealthKit.
Want to know how truly great designers work with the Apple HIG? Let’s watch along as we solve a challenging design issue and use the HIG to guide our decisions.
HealthKit provides iPhone users with a rich set of activity and health data that is available for applications to use. In this video, we will cover the basics of getting access to HealthKit and visualizing a users daily step count. After this video you will be able to query HealthKit data to provide your users with unique and interesting ways to see their activity and general health.
In this screencast, Matt walks us through creating a Queue in Swift using generics to hold arbitrary data types. We'll be learning about collections by creating our own collection type. Watch along as we discuss the Swift language and how to construct a implementation of a custom collection. We'll be going over some guards and guarantees to constrain the types of data in our queue.
You've seen these things in your code. @IBAction. @escaping. @objc. @autoclosure. But what are they? How do they differ from other Swift language features? If you want to understand what is going on under the hood, to know the implications of your code, follow along with Mark Dalrymple in this dive into Swift Attributes.
Implementing Touch ID and Face ID using Apple's Local Authentication framework helps prevent unauthorized access to user's data. We will use the simulator to exercise different authentication scenarios. While the passcode on an iOS device helps prevent unauthorized access, Touch ID and Face ID let the user have a more secure complex pass code, while still making the device convenient to use.

Tight coupling between view controllers in your application can lead to difficult maintenance as you add and remove features. This video will explore how using Protocols can make our Dependency Injection more loosely coupled. This improves the flexibility of the code and makes our application easier to change.
UIStackViews are a relatively new addition to UIKit, appearing with iOS 9. They are quite useful because they eliminate the need for many Auto Layout constraints in common screen designs, making them easier to modify and maintain.
As View Controllers become more complex, the need to manage the state of the view becomes more important. In this video we will discuss how to use a state machine to manage our views state.
Sometimes your app design calls for a control design that isn't provided in UIKit. In this video, we draw one from scratch!
When you have a complex view controller view, sometimes it is helpful to break up the view into manageable chunks. In this video we will show how you can use container views to simplify the construction of certain layouts. After this video you will know when and how to use these container views in your applications.
While Android SDK provides the APIs for using SQLite databases, they force developers to write a lot of boilerplate code. Room solves this problem by creating the glue code that saves objects to SQLite and reads them into memory. In addition, it performs some compile-time checks to ensure correctness of SQL queries.

In this skill pack we'll add test coverage to a full-stack messaging app called ChattrBox. We'll show you a few tools you can use for testing and demonstrate how to configure them to build a test suite that is scalable and provides meaningful feedback about an application.
Ready to dive into the exciting world of tvOS apps? In this skill pack, we'll cover a few examples while introducing you to some fundamentals of programming tvOS applications. By the end of this screencast you'll have the skills needed to start building your own tvOS apps.
In this skill pack, you will learn how to set up and use Sketch for creating color themes, palettes, symbols, and more.
Here are a few sample screencsats to help you get started. View More →
In this screencast, we'll show you how to create a web service for tracking todos and we'll continue to build on this application throughout the rest of the series.
