Swift Assertions

John Daub | May 21, 2018

How to use Swift's assertion functions?

In this screencast, we’ll learn how to use Swift’s assertion function to code defensively. By the end of this video, you’ll be able to use the assertion functions to help you write stronger, more robust code.

Questions we'll answer in this video:

- How can I ensure my code’s assumptions are correct?
- How can I enforce my code’s API constraints?
- What should I do to ensure I cover all possible paths of execution in my code?

Finding and Fixing Memory Issues

7 minutes

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.

Optional Return Values vs. Throwing

8 minutes

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.

Introduction to Breakpoints

8 minutes

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

9 minutes

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.

Automating Breakpoint Actions

7 minutes

While we all love Caveman Debugging, professional developers know their tools inside and out. In this screencast, debugging expert Mark Dalrymple will build on his previous screencast and show you some advanced debugging techniques in Xcode.

Xcode Configurations vs. Schemes

10 minutes

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.

Xcode Inline Documentation

10 minutes

In this screencast, you'll earn how to document your Swift code using Xcode’s Markup support, and Jazzy to create an informative API.

Adopting Configuration Settings Files in Xcode

11 minutes

In this screencast, we will explore how to use Xcode’s Configuration Settings Files - or xcconfig files - and improve our ability to tame the complexity of managing project settings.

Protocol Oriented Dependency Injection

8 minutes

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.

Finding and Fixing Memory Issues

7 minutes

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.

Using Container Views to Manage Complex Layouts

7 minutes

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.
