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. 👌

  • Swift 2 Functions and Extensions

    #189

    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.

  • App Transport Security

    #188

    In this episode we take a look at App Transport Security, which contains new secure-by-default behavior for NSURLSession, NSURLConnection, or any other CFNetwork-based API. We'll see how to diagnose ATS errors, what the recommended settings are, and how to relax the requirements if needed to allow our network connections to be made.

  • Swift 2 Basics

    #187

    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.

  • UIStackView

    #186

    In this episode we talk about one of the coolest new additions to iOS 9: UIStackView. We'll see how to use Interface Builder in Xcode 7 to set up stack views, adjust distribution and alignment, as well as nested multiple stack views for more complex layouts.

  • Self Sizing Cells and Dynamic Type

    #185

    In this episode we'll learn how to implement self-sizing table view cells in iOS 8. We'll also see what the oft-ignored Compression Resistance Priority and Content Hugging Priority are used for, and finally how to implement dynamic type in our application to support dynamic text sizes.

  • DZNEmptyDataSet

    #184

    In this episode we take a look a DZNEmptyDataSet, a useful library for providing a more inviting UI when you have no content to display inside of a table view or collection view. We'll also see how to leverage NSAttributedString to provide styling of the text that is displayed on the screen.

  • Screen Savers Part 2

    #183

    Sam Soffes continues building a screen saver, this time showing us how to add a Preferences window to the app as well as exporting and installing it as a real screen saver in the system.

  • Screen Savers - Part 1

    #182

    In this episode Sam Soffes walks us through creating a screen saver for OS X. In order to develop it and see the results quickly, he starts by creating a preview Mac app to show what the screen saver will look like.

  • CGImageSource

    #181

    In this episode we take a look at CGImageSource from the ImageIO framework. Using CGImageSource we can perform operations like resize without loading the entire image into memory. In addition, we can extract image metadata like f-stop, aperture, ISO, and camera/lens information.

  • Advanced NSOperations

    #180

    Deep Dive with NSOperation

    In this episode, Ben continues exploring NSOperation-based architecture, this time writing operations that present UI for a login screen, load the Core Data stack, and operations that are composed of multiple lower-level operations.

  • Carthage for Library Authors

    #179

    Sam Soffes joins us again to talk about supporting Carthage for your own libraries. In the demo, you'll also see how to structure a project to include both Mac and iOS framework targets with a single Xcode project.

  • Getting Started with Carthage

    #178

    In this episode we welcome our first ever guest screencaster, Sam Soffes! Sam takes us through what it takes to get started with Carthage to manage dependencies. Sam compares Carthage's approach to CocoaPods and walks through how to bring in a 3rd party library into a project.

  • NSOperation Dependencies

    #177

    Deep Dive with NSOperation

    In this episode we discuss dependent NSOperations. Using dependencies you can queue up a bunch of jobs and they will be run in the correct order, having one provide the necessary state for the next one to run. In the example, we take the large Hubble image, scale it down to a more appropriate size, then apply a Core Image filter to it. Each operation is dependent on the one before it, yet they are all queued up at the same time.

  • Asynchronous Operations

    #176

    Deep Dive with NSOperation

    In this episode we examine the asynchronous (a.k.a concurrent) type of NSOperation where we are doing things that involve callback blocks or delegates.

  • NSOperation Basics

    #175

    Deep Dive with NSOperation

    In this episode we take a look at the basics of NSOperation, NSOperationQueue, starting from block operations and moving to custom NSOperation subclasses. We'll also see why it's important to make your operations thread safe.

  • Local Notifications

    #174

    In this episode we cover local notifications in iOS 8. We cover the difference between count-down style notifications and time-zone based notifications. We also discuss how to add actions to the notifications and handle those in your application.

  • Interactive Magic Move

    #173

    In this episode we take the Magic Move transition from last week's episode and make interactive, so that you can feel the transition along with your swipe.

  • Magic Move

    #172

    In this episode we'll create a custom view controller animation that mimics the Magic Move behavior from keynote, taking one object and animating into its place on the next slide (or view controller).

  • NSDateComponents

    #171

    In this episode we examine how we can leverage the NSDateComponents class to convert a set of individual date parts like month, day, year into an actual NSDate

  • Testing with Quick

    #170

    In this episode we talk about a Swift testing framework called Quick. Quick offers a familiar BDD style syntax, some really friendly matchers, as well as support for testing asynchronous parts of our code. We'll use a Ninja class as our example, testing initialization, equality, and an asynchronous method.

  • Road Trip DJ - Part 14 (Final)

    #169

    Road Trip DJ

    In this episode we wrap up our long Road Trip DJ Series. We resume testing on the device, uncovering and fixing an auto-layout issue, working with the music players events to keep our UI in sync, implementing a song progress indicator and implementing scrubbing. Phew!

  • Road Trip DJ - Part 13

    #168

    Road Trip DJ

    In this episode we fix up the scrollbar, handle taps and update the active track, as well as adding a background color to the active row.

    Road Trip DJ

    In this episode I do some deep auto-layout constraint debugging with Reveal, and discuss how to make our header resize based on the device we're running on.

  • Road Trip DJ - Part 11

    #166

    Road Trip DJ

    In this episode I address the usability concerns of our toolbar buttons. I removed the bar button item spacing elements and instead use auto layout to control the size of the buttons. We also add a visual indicator of how wide each button is when you tap it, and fix the play/pause state of the middle button.
