NSScreencast (free videos)

Now that we've seen a taste of SwiftUI, let's dive into a real example and build an app. We'll have a first look at @State variables we can use to creating a binding between our state and our UI, and we'll run into a few puzzling errors and see how we can coax Xcode into giving us the right error message.

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 hon...

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.

In this episode we look at how to generate a certification for adding push notification support for your app, using OneSignal as our push notification provider

In this episode we will setup iTerm2, profiles, custom color schemes, and fonts.

In this episode we look at some of the basic system preferences on macOS High Sierra. We set up the Dock, Keyboard shortcuts, and show how to customize key repeat timing outside of the preferences window.

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...

The first episode in a new series on CloudKit, here we see how to setup our project to use CloudKit as well as how to create and save our first record.

In this episode I am joined by Soroush Khanlou. Together we pair up to implement the Poker Hands Kata. We start off by parsing the raw string input into structured types, complete with tests.

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.

In this free episode, Ben explores Swift 2 functions, how argument labels work, returning tuples, the guard clause, as well as extending behavior on core types.

In this episode we take a look at Swift 2's basic types such as Int, Double, Bool, Array, and Dictionary. This episode is part of a series covering Swift 2 from a beginner's perspective.

Continuing our build out of Road Trip DJ, this time I focus on the music player, and keeping the play/pause button in sync on UIToolbar, which proves to be more difficult than it should be.

In this episode we continue Road Trip DJ and implement the media picker controller, talk about the different modes that in can operate in and how that affects the usability of this app. We also consider how we're going to build a playlist and keep appending items to it.

In this episode we start building an app from scratch called Road Trip DJ. The idea is the build a playlist of music on the fly while it is playing. This is an app I've wanted to build for a while and it serves as a good, small app we can build from start to finish.

In this episode we cover a basic but fundamentally important topic: dealing with dates & times. Particularly when dealing with an API, dates can arrive in all shapes and sizes. We'll examine some of the common ones, talk about how to parse these formats into NSDate instances, and how to use NSDateFormatter to display them back again as a string.

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?

To celebrate the launch of iOS 7, here is a bonus free screencast covering a few of the concepts in iOS 7 such as the status bar behavior, tint color, and navigation bar transitions. We'll also take a look at Xcode 5 with a couple of the new features, including the integrated test runner.

We continue with our example chat application here and add the ability post a message, poll for updates, and receive push notifications. This episode utilizes a pod calles MessagesTableView controller to present an SMS like interface for the messages.

This week we take a look at Windows Azure Mobile Services, a back-end for mobile applications that has first class iOS support. In this episode we begin building a full featured chat application. This is part 1 of 2, in which we set up a new mobile service, wire up the SDK with CocoaPods, set up Twitter authentication and enrich the data using Javascript on the server. This episode has been sponso...

In this episode, we'll create a CocoaPod out of the modal picker view component we created in episodes 25 & 26. We'll see how to tag & push our code to a github repository and create a podspec so that others can use this component in their projects.

The latest version of the LLVM compiler supports some excellent new syntax additions to the Objective-C language. In this episode, I cover what the new syntax is, how to use it, and a few caveats to look out for.

HTTP Caching is an important concept to understand when building iPhone apps that consume HTTP APIs. In this episode, we'll see how leveraging Etags, Last Modified dates, and Cache-Control headers can help make your app more efficient and tolerable to use.
