×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.…
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.…
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.
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.…
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!…
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.…
In this episode we will talk about the overview and motivation for a modular project architecture. Why split things up? I'll talk about the problems we face, what benefits we may achieve, and how can we approach the problem.
One of my favorite new features of Xcode 13 is support for Vim key bindings. In this episode we will see how to enable this and I'll give a quick tour of how to get around using Vim.
In the next few episodes we will explore the concept of Protocol Witnesses. This is an advanced topic that can be somewhat hard to approach, but in learning about Protocol Witnesses you will see how we can leverage the Swift language and functional programming to do some really cool things.
Context menus are a great affordance for performing related actions to a UI element. Users can tap and hold to view the context menu, and the gesture is consistent across the OS so users will likely already be familiar with it. In this episode we'll show how to set up a basic context menu with a custom preview with normal and destructive actions.…
This is a discussion and code overview of another implementation of mapping models using key paths with a special guest, Antoine van der Lee! In this episode we talk about his initial goals and constraints, and some of the design tradeoffs he made while designing a solution that would give him a bidirectional mapping between Core Data entities and other model types.…
In this episode we review the basic example app and start setting up our collection view in code. We start with the basic flow layout which is most common. Later we'll refactor this to use the newer style, but this episode introduces the series and sets up the foundation we'll build upon.
In this episode we migrate our collection view to use the new cell registration API. Using this API we no longer need to cast dequeued cell types to our custom types. Instead, we set up the registration object with the cell type and the data we'll be passing to each cell. This further reduces the code we have to write in our datasource implementation and gives us more flexibility on how and where cells are configured.…
With UITableView no longer being encouraged for use, we need to replace this behavior with UICollectionView. This is where UICollectionViewListLayout comes into play. Using this layout we can get the familiar table view appearance in plain and grouped styles (as well as additional styles to support sidebars on iPad and macOS). This includes support for sticky headers and footers, swipe actions, and other UITableView behaviors that we've come to rely on.…
First introduced in iOS 13, UICollectionViewCompositionalLayout is an amazing and powerful addition that gives you lots of flexibility when describing layouts. There are a few new types to get used to (namely sections, groups, and items) but they all work together allowing you to keep layout separate from your views and your data.…

UITableView can support scrolling through many rows of data, however fetching large amounts of remote data can slow down your app, use up too much memory, and bog down your web server. This is all wasteful if users aren‘t ever going to scroll down that far. In this episode you‘ll learn how to perform automatic UITableView pagination using an easy technique.…

In order to use CloudKit to read or write private data (or to write in the public database) the user will have to be signed in to iCloud on their device. If they are not, they'll not have a great experience, and things won't work. In this episode we'll check the account status before trying to save a record in CloudKit. We'll also respond to the notification to know when the user's account status has changed so we can react accordingly.…

In this free episode, we take a look at a core Swift 2 feature: Optionals. Unlike Objective-C, where nil is considered a no-op, in Swift nil is specifically recognized by the compiler, which forces you to handle cases where nil might be present in a variable.

This week we have another free bonus video on the improvements that Xcode 5 brings to Autolayout. As something that has been quite obnoxious to work with in the past, many people dismissed auto layout when it was introduced to iOS 6. With these improvements it is much more friendly and dare I say... usable?…

iOS 14 Beta is now available and one of the new features is Lazy stacks. With a normal stack, all the layout happened at once, which meant poor performance for large lists of content, grids, etc. With Lazy stacks the views are only created when they first come on screen, greatly increasing the usefulness of stacks for large or infinite collections of content.…

Before Swift 5 we used to write our own Result type to contain a value or an error (but never both). A lot of 3rd party libraries brought along their own as well. Then Swift 5 came and brought us Result. Not only is it slightly different than the ones we might be familiar with, Swift's Result type also has some useful functionality up its sleeve.…

Sometimes we need to create variants of our icons. This can be done by using template images and using a UIImageView with a tintColor change, however sometimes this isn't feasible. We can use our icons along with a mask to create new images of whatever color we want. In this episode we'll use UIGraphicsImageRenderer to quickly draw a new dimmed image for a highlighted button state.…

SwiftUI's declarative nature makes building UIs incredibly easy. In this episode we will build a wallet UI with cards. We will create a CardView so we can reuse it in multiple places. Then we will use transforms to alter it's size and position. Finally we will see how declarative animations work as we expand the cards apart.…

Back from WWDC 19 and blown away by the announcements. There's a lot to cover, but we'll start by digging into the most exciting announcement: SwiftUI. This is going to change everything...
Working with dates is a task that is universally applicable to Swift developers. Particularly when dealing with an API, dates can arrive in all shapes and sizes. We‘ll examine some of the common ones such as ISO 8601, show how to parse these formats into Date instances, and how to use DateFormatter to display them back again as a string. We‘ll also cover the importance of using en_US_POSIX and honoring the user‘s Locale when displaying dates.…
In this episode we configure our iOS app to receive push notifications, adding the OneSignal SDK to our project, configuring the Notification Service extension, and testing it out on a real device.
