Sometimes your app design calls for a control design that isn't provided in UIKit. In this video, we draw one from scratch!
Throwing errors and completion handlers have pros and cons, and can’t be used in all situations. Here we examine some strategies for writing elegant async error-handling code with closures and associated-value enumerations.
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.
Incorrectly managing memory in our applications can result in hard to find bugs and possible crashes. In this video, we will explore the Memory Graph debugging tool in Xcode and how you can use it to find and fix strong reference cycles in closures.
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.
Performing tasks when an application is first launched is a common practice to give users important information about the application. In this video, we will discuss one technique for implementing first launch logic, as well as how to quickly test this code.
