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. 👌

    Modular Project Architecture

    One big benefit of modularizing an application is working on features as modules. Let's re-create the welcome screen experience as a feature module using Swift Package Manager and Xcodegen.

  • #504

    Modular Project Architecture

    In this episode we create a modularized setup where our modules are Swift Packages and brought into the main app using Xcodegen and local path references to the packages.

  • #469

    Command Line Swift

    Now that we have some streaming output from the ffmpeg process, we can take this and create a custom progress bar. Since this could useful in other utilities we can create it as a separate Swift package and import it using a local file reference.

  • #468

    Command Line Swift

    When dealing with long running tasks it would be nice to be able to gather output as the task runs and not hang until the entire process is done. In this episode we will extract some useful information out of ffprobe, so we can get the total number of frames in a video file, and then kick off ffmpeg to encode the video. We'll use the Subprocess package to provide a simpler interface over gathering output from a pipe as it is sent, rather than waiting for the end.

  • #466

    Command Line Swift

    In this episode we will launch other programs as sub processes and show how to capture its output.

  • #465

    Command Line Swift

    Working with files and folders with FileManager is cumbersome. Instead we'll lean on the excellent Files package from John Sundell.

  • #464

    Command Line Swift

    I use a collection of command line scripts that help me in the production of NSScreencast episodes. Most are written in Ruby, which is a language I know and love, and some are written in bash, which is... a language. I sometimes wonder what these scripts would look like if I were to write them in Swift. So in this new series I'm going to explore rewriting a script that I use to encode videos using Swift. In this episode we'll bring in the excellent Swift Argument Parser library and use it to give us a clean and consistent command line interface to start with.

  • #460

    Managing dependencies can be a pain. Unless you're using shared instances accessible everywhere, you end up having to pass along dependencies from class to class. One strategy for decoupling your types from external dependencies is to create protocols and "inject" the actual concrete implementations at runtime. This enables you to test them easily and also isolates library-specific APIs from the rest of your application. This can make switching between libraries more feasible. In this episode we'll take a look at a library called Resolver that does this. Technically it implements Service Location rather than Dependency Injection, but the result is similar.

  • #420

    Now that Swift Package Manager has started to see some adoption and we have some integration inside of Xcode, I think it's time to take a deeper look at how to use it both as a consumer and as a library author. In this episode we'll create a DiceKit library using SwiftPM, then use it in a command line utility.
