    #605 - Profiling and Removing Splits

    The initial, naive solution for the 1 Billion Row Challenge, which involved splitting strings by separator and semicolon, parsing cities and temperatures, and then collecting and outputting data, ran in approximately 11 minutes. This time we profile our solution to see where the time is spent. We find some quick wins for optimization and drastically improve the run time.

    #604 - Billion Row Challenge - Intro

    In this episode, I am thrilled to be joined by Matt Massicotte to kick off the "1 Billion Row Challenge" in Swift. The goal is to efficiently parse a massive file containing weather station data and calculate the min, max, and mean temperatures for each city. We set up a Swift package, explore basic file I/O methods, memory mapping, chunked reading, and implement a naive solution that processes the data and sets the stage for significant optimization in upcoming episodes.

    #591 - Getting Started with AudioKit

    We'll first take a look at the AudioKit Cookbook application, which is a great way to see what is possible. Once we've seen some of the capabilities we can look at the code to get an idea of how to build things with AudioKit. We'll then add a package collection in Xcode to make bringing in the various AudioKit package dependencies a little easier.

    #590 - Audio Fundamentals

    We kick off a new series on audio programming for iOS using AudioKit. Before we jump into code, however, it is important to get a foundational understanding of how audio works and how it is represented by the audio hardware (sound cards, etc) that the software integrates with. In this episode we will talk about the fundamentals of audio, learn some essential terminology, and look at some real world audio equipment so we can better understand the mental model behind AudioKit.

    #553 - Mastodon Post UI and HTML Parsing

    In this episode we tackle showing a list of posts, which requires us to convert the network models into models more fit for the UI, parsing HTML in order to display as an AttributedString, and displaying the author information.

    #531 - SwiftUI Escape Hatch

    Sometimes we run into issues where SwiftUI doesn't quite do what we need. In some cases, SwiftUI views are powered by UIKit under the hood. Wouldn't it be great (and devious) to dig into the underlying UIKit views to customize things when vanilla SwiftUI just won't cut it? In this episode we'll look at a technique for discovering the UIKit underneath SwiftUI views.

    #526 - Hot Reloading with Inject

    One of the most impactful things you can do to improve productivity is to improve turnaround time when iterating on features. Playgrounds and Xcode Live Previews are great, but both have their limitations. In this episode we will explore how to utilize hot module reloading to have the simulator automatically reflect your changes when you save. It's magic, and will blow your mind!

    #501 - Nested Xcode Projects

    One way of achieving modularization is to build frameworks using nested Xcode projects. This has the benefit of having everything in one place and can easily build the entire thing. You can also zero-in on a single project and just work from there if you want. Each sub-project can have its own tests, sample application, etc.
