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. 👌

  • Road Trip DJ - Part 10

    #165

    Road Trip DJ

    In this episode we adapt MPMediaItem to our PlaylistItem protocol and fix some issues related to running on the device. We add play/pause functionality, and discuss the issue of hit area on our toolbar buttons.

  • Road Trip DJ - Part 9

    #164

    Road Trip DJ

    In this episode I fix a couple of bugs and fix the transition animation for the header view by leveraging UIView snapshotting.

  • Road Trip DJ - Part 8

    #163

    Road Trip DJ

    In this episode we fix the playlist header at the top, first by a custom collection view layout, then by simply using a custom view at the top.

  • Road Trip DJ - Part 7

    #162

    Road Trip DJ

    In this episode we wire up the next / previous track buttons and modify which track is currently shown in the header. We also encounter an unexpected issue when comparing signed and unsigned integers.

  • Road Trip DJ - Part 6

    #161

    Road Trip DJ

    In this episode we make a custom collection view header to prominently display the currently playing track. We also fix up some auto layout issues from the last episode.

  • Road Trip DJ - Part 5

    #160

    Road Trip DJ

    This time we work on the collection view layout and cells, along the way we create an abstraction of our media items to make development go a bit faster and to allow the app to display content in the simulator.

  • Road Trip DJ Part 4

    #159

    Road Trip DJ

    In this episode I put some custom icons in the player bar and convert this into a control that can be displayed in interface builder, complete with configurable spacing between buttons using Interface Builder.

  • Road Trip DJ - Part 3

    #158

    Road Trip DJ

    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.

  • Road Trip DJ Part 2

    #157

    Road Trip DJ

    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.

  • Road Trip DJ Part 1

    #156

    Road Trip DJ

    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.

  • xcconfig Files Part 2

    #155

    Continuing from last week's episode, this time we talk about adding environment-specific settings in xcconfig files, have them pre-processed into the Info.plist, and also how to integrate this technique with CocoaPods.

  • xcconfig Files

    #154

    In this episode we extract all of the settings from a standard iPhone project and move them over to a .xcconfig file for Xcode to use as a base for our projects. Doing so can make our configuration a bit more explicit, allow us to add comments on why certain settings are necessary, and also to put them under version control to make it easy to spot changes.

  • Feature Toggles

    #153

    In this episode I cover configuring your Xcode project to conditionally include or exclude a feature, in case there is a feature you can't have in the App Store, or perhaps something that isn't quite ready yet.

  • Cocoa Bindings

    #152

    In this episode I take a look at the basics of Cocoa Bindings. With Bindings you can have your controls on your view bound to properties on your controller or model, and even have controls bound to themselves. What would normally be a lot of manual plumbing code is handled for you automatically by bindings. To demonstrate, we build a live-updating temperature converter.

  • CABasicAnimation

    #151

    In this episode we take a look at CoreAnimation's easiest form of animation with CABasicAnimation. Using this class we can animate properties of a layer, such as frame, background color, paths for CAShapeLayer, and more. We also cover timing functions and how to make a transition between shapes a bit easier for the system to interpolate between.

  • Cocoa Windows

    #150

    In this first episode covering OS X development, I cover how to manage windows, window controllers and xibs with Objective-C and Swift. There are lots of options (and opinions) here, so we follow some advice from Mike Ash's blog post on the topic.

  • How Bézier Paths Work

    #149

    Have you ever wondered how bezier paths work? What are the control points, and how exactly do they affect the line? In this episode we'll build our own visualization of how a bézier path is constructed to help understand it better.

  • Function Composition with CI Filters

    #148

    We continue our example of CoreImage CIFilters, this time showing how function composition can facilitate working with filters a bit more flexible and chainable. Starting with the imperative, method-based approach, then gradually building towards a pattern that allows us to easily build filters functionally, swapping out the order, and changing around input parameters.

  • Core Image

    #147

    In this episode we take a look at Core Image, Apple's image framework for image effects on iOS and Mac OS X.

  • Vibrancy and Blur

    #146

    In this episode I revisit the blur technique we covered in episode 104 and re-implement it using iOS 8's Visual Effect view with UIBlurEffect and UIVibrancyEffect.

  • Share Extensions Part 2

    #145

    In this episode we continue our building of a share extension. This time we focus on performing the actual upload in the background, sharing a background session with our application through the App Group capability.

  • Share Extensions Part 1

    #144

    In this episode we create an application and share extension that lets us post to the Imgur API. We use a Framework to share API code between application and extension, and we leverage App Groups so that background sessions transfer across both as well.

  • Flat Map

    #143

    In this episode we cover a horribly named, yet fairly powerful concept called flat map. We'll use this technique to solve the problem we discovered last time dealing with Result<T> and having to use a switch statement everywhere.

  • Error Handling in Swift

    #142

    In this episode I talk about the pattern of communicating errors in Cocoa and how it can be improved by leveraging features in Swift. By introducing a Result type that is generic and applies to any type, it appears useful, however we run into some cumbersome use cases that will require further discussion.
