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. 👌

  • Nested Xcode Projects

    #501

    Modular Project Architecture

    One way of achieving modularization is to build frameworks using nested Xcode projects. This has the benefit of having everything in one place and can easily build the entire thing. You can also zero-in on a single project and just work from there if you want. Each sub-project can have its own tests, sample application, etc.

  • Motivation for Modular Project Architecture

    #500

    Modular Project Architecture

    In this episode we will talk about the overview and motivation for a modular project architecture. Why split things up? I'll talk about the problems we face, what benefits we may achieve, and how can we approach the problem.

  • Localizing Pluralized Phrases

    #499

    Localizing Your App

    Pluralization rules vary by language, so it's not as easy as just adding an "s". To properly handle these cases, we need to use a Stringsdict file and format our string using a special syntax.

  • Localizing Images

    #498

    Localizing Your App

    Sometimes you may find that you want to localize images specific to a locale. In this episode we'll make up a contrived example where we want to change our splash image from a pizza to sushi if the locale if Japanese. We can easily do this with Asset Catalogs and provide a more tailored experience.

  • Importing Translated Strings

    #497

    Localizing Your App

    Once we have our translated files back from our translators, we can now import them for use in our project. I'll show how do do this within Xcode and from the command line.

  • Exporting Strings for Translation

    #496

    Localizing Your App

    In this episode I will show two ways you can export all of the strings in your project. The first is using Xcode, but since this is a process you'll likely want to repeat, we'll also show how to do it via the command line so you can automate it. We'll then take the xliff files and send them off for translation using a translation service.

  • Preparing your project for localization

    #495

    Localizing Your App

    There's a bit of prep work we need to do to get our project ready to be localized. We'll start by defining which languages we want to support, localize any interface-based files like Storyboards, and then move on to localizing strings in code.

  • Localizing Dates and Times

    #494

    Localizing Your App

    Using DateFormatter we can format dates and times to whatever format we choose. However, in most cases we should rely instead on the builtin styles instead, which are locale aware. This way we can present dates and times that are consistent with the user's preferences.

  • Locales, Numbers, and Lists

    #493

    Localizing Your App

    Let's quickly review how to work with the Locale object. Then we can use various locales in conjunction with NumberFormatter and ListFormatter to have localized output provided for us.

  • Localization 101

    #492

    Localizing Your App

    In this episode we will define what Localization is and why you should localize your apps.

  • Xcode 13 Vim Mode

    #491

    One of my favorite new features of Xcode 13 is support for Vim key bindings. In this episode we will see how to enable this and I'll give a quick tour of how to get around using Vim.

  • Introducing the Swift Coding Library

    #490

    Codable Witnesses

    In this episode we introduce a new open source library called Swift Coding that takes all of these concepts and wraps it up into a Swift Package you can use in your own projects. We give a tour of what the library can do and how you can use it.

  • Deferred Context Menus

    #489

    Working with Context Menus

    Sometimes we need menus to be dynamic, or we need to fetch some data before being able to build out the menu items. In this episode we will see how to leverage UIDeferredMenuElement to fetch some data and build a dynamic menu.

  • Codable Witnesses for Decodable

    #488

    Codable Witnesses

    Last time we talked about the Encodable protocol. This time let's look at the Decodable protocol. We explore the general concept, then introduce zip and map as utilities to compose smaller decodings into larger ones.

  • Exploring Witnesses for Encodable

    #487

    Codable Witnesses

    We start exploring the concept of converting Encodable into an Encoding protocol witness. We discover how to clean up our code and make it fit in with `JSONEncoder`’s existing API. We then break down our example into smaller pieces and discuss how we can leverage pullback and functional composition to build bigger pieces out of smaller ones.

  • Intro to Protocol Witnesses

    #486

    Codable Witnesses

    In the next few episodes we will explore the concept of Protocol Witnesses. This is an advanced topic that can be somewhat hard to approach, but in learning about Protocol Witnesses you will see how we can leverage the Swift language and functional programming to do some really cool things.

  • Context Menu Previews

    #485

    Working with Context Menus

    Let's see how we can provide a custom view controller to preview when a context menu is opened. This is analogous to (and a replacement for) the Peek/Pop interaction for devices that supported 3D Touch.

  • Table View Menus

    #484

    Working with Context Menus

    Another common use of context menus is with table views and collection views. In this episode we will explore adding a menu to a table view cell that allows copying a font or toggling it from a favorites list.

  • Nested / Inline Menus

    #483

    Working with Context Menus

    In this episode we will see how to nest menus inside each other as well as dynamically choosing when to show a nested menus contents inline.

  • Basic Context Menus

    #482

    Working with Context Menus

    Context menus are a great affordance for performing related actions to a UI element. Users can tap and hold to view the context menu, and the gesture is consistent across the OS so users will likely already be familiar with it. In this episode we'll show how to set up a basic context menu with a custom preview with normal and destructive actions.

  • Mapping Models with Antoine van der Lee

    #481

    This is a discussion and code overview of another implementation of mapping models using key paths with a special guest, Antoine van der Lee! In this episode we talk about his initial goals and constraints, and some of the design tradeoffs he made while designing a solution that would give him a bidirectional mapping between Core Data entities and other model types.

  • Mapping Models with Keypaths

    #480

    Ever wanted to translate from one type to another, for instance mapping from network models to core data objects? In this episode we will explore how to leverage Swift Keypaths to create a mapping between models. Along the way we'll run into a limitation of key paths and then talk about how to work around it.

  • Easier Styled Strings with BonMot

    #479

    Layout in Code

    Working with NSAttributedStrings can be a bit cumbersome, and can present some challenges when you want to localize your strings. We can make things much easier to work with by leveraging the BonMot library, which provides a cleaner interface for styling strings, allows us to separate styling from the views and strings, and customize tags we can use to mix styles in the same string.

  • Handling Links in Text

    #478

    Layout in Code

    Sometimes our text contains links that should be styled differently and react to taps so a URL can be opened in a web browser. While we can use a UILabel to detect and style links, they don't respond to touches. Let's see how we can leverage UITextView instead to handle links in NSAttribtedStrings.
