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.

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.

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

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

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

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

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

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

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

    In this episode we are joined again by Conrad Stoll

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #195

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

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.

  • #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.
