Have I mentioned lately how awesome NSScreencast is? No? Worth the subscription. Check it out if you’re an iOS developer. Or even if you’re not and you want an example of how to do coding screencasts well.

Foster Bass

Got tired of dead-end googling so I checked to see if @NSScreencast had covered what I was looking for. Of course he had, 4 years ago. Should have checked there first.

Aijaz Ansari

One 13-minute episode of @NSScreencast just paid for the yearly subscription fee in amount of time saved. Do it.

Sam Soffes

Seriously great stuff even for seasoned developers. I’ve learned a good amount from Ben’s videos.

James Dempsey

You can really expand your development horizons in just a few minutes a week with NSScreencast.

Alexis Gallagher

Random PSA for iOS developers: @NSScreencast is a great resource, and worth every penny. It’s high quality, practical, and honest.

Nate Armstrong

Can’t say enough good things about @NSScreencast There is gold in the Road Trip DJ Series.

Karl Oscar Weber

I just reuppped my subscription to @NSScreencast. [An] indespensible resource if you’re into iOS or Mac Development.

Marcus Ziadé

Just finished @NSScreencast series on Modern CollectionViews. Strongly recommended. Programmatic UI, nicely structured code, easily approachable explanation style. 👌

  • Icon Badging with Fastlane

    #213

    When doing release builds it is handy to automatically update the build number so we always have a unique version for reporting bugs. However it is not easy for testers to always know which version they are testing. In this episode we'll look at how to set up versioning for our project, automatically increment the versions number for release builds, and badge our application's icon so it is easy to see which version of the app you have installed.

  • Fastlane

    #212

    In this episode we set up fastlane to automate a lot of the tedious tasks related to building and deploying iOS applications. We use it to create our bundle identifier, create certificates and provisioning profiles, build and test our app, take screenshots on multiple devices, and submit to TestFlight.

  • Indenting Text with Text Kit

    #211

    Sam joins us again to cover how to change text layout dynamically as you type. He will implement a feature common in Markdown editors where typing dash followed by a space indents the list. In the process you'll learn about more of the Text Kit API. If you've ever wondered what type of work goes into building a text editor, this episode is for you!

  • Cool Text Effects - Part 2

    #210

    Continuing on from last time, we take our glyph layers and apply Core Animation, providing for some interesting effects including animating the stroke of each glyph path and applying a typing effect with transforms.

  • Cool Text Effects

    #209

    In this episode we dive deeper into the text system, leveraging CoreText to compute exact metrics about each glyph in a string. We can use this information to do interesting things with text. There's a lot of code in this one, but you'll learn the basic foundations of text, how CoreText works, and how to extract metrics and paths from your rendered text. We'll use this in a future episode to implement some interesting effects!

  • Syntax Highlighting with TextKit

    #208

    In this episode Sam Soffes joins us again to show how to implement some rudimentary syntax highlighting of text while you type using TextKit. This builds on the concepts we learned in episode 207, so start there first!

  • Intro to Text Kit

    #207

    In this episode Sam Soffes walks us through the basic components of TextKit, a framework that allows complete control over the text layout and rendering system on iOS and OS X. TextKit is a complex topic, but with it brings a lot of power. This episode will cover the basics that we can build upon in future episodes.

  • More TableView Customization

    #206

    In this episode we continue with our Starcraft II Guide application, this time focusing on using a table view to edit a model. We leverage a cell with a text field, a cell to select data from another view controller, and a section that is only editable/reorderable with itself.

  • TableView Customization

    #205

    In this episode I take a stock UITableView and UINavigationController and customize their appearance to match a design for a Starcraft II companion app. We'll leverage Swift enums to capture colors & fonts so we can reuse them in multiple places. We will also utilize the UIAppearance API to style all instances of a UINavigationBar, and get rid of UITableViewCell's default separator indentation.

  • JSON API Client - Part 2

    #204

    In this episode we start writing an application-specific API Client. We use Argo to decode our JSON response into an Episode model, including some nested object decoding, date formatting, and wrap it up by testing the implementation to make sure it works.

  • JSON API Client

    #203

    In this episode I start creating a reusable api client that will make it a lot easier to consume a JSON api and convert the response into model objects. It uses Argo for the JSON parsing, and leverages Swift features to provide a rich callback for the API calls.

  • Building a WatchKit Complication

    #202

    In this episode we are joined again by Conrad Stoll

  • Building a WatchKit Glance

    #201

    In this episode Conrad Stoll joins us once again to extend the watchOS 2 app to include glance, indicating to us when our beer will be ready. He leverages a new timer class that allows you to accurately display a countdown (or count up) timer that runs completely on the watch.

  • Building a WatchKit App

    #200

    In this episode we are joined by Conrad Stoll who shows us how to build a watchOS 2 app to order beer. Data is synchronized from an iOS app, and the digital crown is used to make selections.

  • NSSTV Part 2 - Icons and Artwork

    #199

    In this episode we use Sketch to export top shelf artwork and layered icons for tvOS. We then preview the layered artwork using the Parallax Previewer tool. We then add these to our asset catalog in Xcode to add them to our application.

  • NSSTV Part 1 Project Setup

    #198

    In this episode we start a new series on building the NSScreencast tvOS application. We'll start off by creating the Xcode project, initialize our Gemfile and Podfile for dependencies, as well as talk about a few ways of getting around issues where a 3rd party library doesn't indicate that it supports tvOS yet.

  • Mastering TV Focus

    #197

    In this episode we take a deep look at how focus works with tvOS. We learn how to use UIFocusGuide to redirect focus when the engine cannot find an appropriate element to focus. We also learn some debugging tricks on how to visualize focus moves using Quick Look, and how to use _whyIsThisNotFocusable to troubleshoot lack of focus. Finally we'll learn about custom focus animations and layered images.

  • CAReplicatorLayer

    #196

    In this episode we take our missile animation from last time and update it to use CAAnimations. Using these animations we can add a wiggle, along with a small oscillating rotation to give a little life to the missile. Then we utilize CAReplicatorLayer to have them fan out and fire in slightly different directions.

  • Intro to Apple TV

    #195

    In this episode we dive into tvOS, creating a spaceship dashboard application, complete with animated rockets and a crew list. Ludicrous speed, go!

  • Modeling API Endpoints

    #194

    In this episode we talk about modeling API Endpoints as first class types, rather than relying on strings and string interpolation scattered across your application. For this we'll leverage Swift enums with associated values.

  • In App Search

    #193

    In this episode we take a look at how to provide deep search in our iOS applications. We start by leveraging NSUserActivity to provide relevant search results for recent activities to users. Then we look at how to customize the search results with rich metadata. Finally we look at using CoreSpotlight to fully index the content to make it available for search after we launch our app.

  • Handoff

    #192

    Supporting Handoff in your iOS / Mac applications can really delight users. In this episode we will build handoff support into an application so that users can continue their task on the web, or in a separate Mac application that is registered to handle that task.

  • Swift 2 Optionals

    #191

    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.

  • Custom URL Protocols

    #190

    In this episode we look at how to create a custom NSURLProtocol to intercept and alter a network request. This can be useful to provide application-wide interception & logging of network requests, alter requests to change parameters or add authentication, sign requests, or to handle custom url schemes.
