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.
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.
We demonstrate using Dispatch Groups to rendezvous multiple simultaneous asynchronous tasks so that you can process all of their results at once, after the last one finishes.
Sometimes your app design calls for a control design that isn't provided in UIKit. In this video, we draw one from scratch!
This video Illustrates the differences between using optional return values or throwing errors for functions that can fail. The implementations are discussed and the pros and cons of each approach are discussed.
