This week, let’s take a look at a few examples of building custom debugging utilities for SwiftUI-based views — from specific methods to general-purpose abstractions.
When writing tests for any application, it's always important to consider what the debugging experience will be like when they eventually start failing. This week, let's take a look at a few different scenarios, and how we - with just a few subtle tweaks - can make our tests a lot easier to debug.
Using the new os_signpost API, we can easily place markers - signposts - in our code that can make profiling and debugging performance issues a lot simpler. In today's WWDC update, let's take a look at how to get started with this new tool!
Carola Nitz joins John to talk about LLDB and debugging, her work on the open source VLC app, how she got her previous job at Apple, and much more.
While launch arguments are probably most commonly used as input to command line tools - this week, let's take a look at how we can also use the power of launch arguments when working on, debugging, and testing an iOS app.
Marin Todorov and Florent Pillet, two of the four authors of Ray Wenderlich's RxSwift book, join John to talk about Rx, reactive programming, debugging, learning new technologies and much more.
