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.
A breakpoint is a debugging tool that lets you stop your application at a specific line of code. The application is suspended, allowing you to look at your program state, and collect information about whatever bug you are tracking. In this screencast, we'll talk about simple breakpoints, conditional breakpoints, and set exception breakpoints.
Generational Analysis with the Allocations Instrument can be used to track down memory growth issues. We're going to be tracking down a memory management issue that caught us here at Big Nerd Ranch by surprise, and we'll show you what we did to solve it.
In this screencast, we’re going to look at how to write your native iOS code for React Native in a more idiomatic Swift way. By the end of this screencast you’ll be able to refactor your React Native Objective-C code to be Swift code that isn’t React Native specific.
In part 1, we began simplifying our React Native native iOS code by separating an idiomatic Swift class from a React Native adapter. We’re going to finish this extraction by moving over a method that returns data. By the end of this screencast you should be comfortable with writing idiomatic Swift methods that return data synchronously or asynchronously, and adapting them to React Native.
Targets and configurations and schemes; Oh my! Confused by these Xcode concepts? Curious how using multiple build configurations coupled with schemes can avoid the multiple-target mess? If you’re wondering what this all means and how it can make your developer life better, this video is for you.
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.
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.
