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. 👌

There are 7 episodes with tag 'foundation'   Clear search
  • Date formatted() - a Hidden Gem

    #566

    With many great features announced each year, it's easy for smaller changes to go without as much fanfare. In this episode we'll take a look at a new way to format dates using the .formatted() API. It's easy to use, expressive, and best of all we don't need to worry about caching formatters anymore!

  • 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.

  • 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.

  • Styling Text with Attributed Strings

    #477

    Layout in Code

    To work with styled text we'll use NSAttributedStrings, which allow us to apply styles to ranges of text. Doing this in code is a bit more cumbersome than in storyboards, but allows us to control things like font size, color, style, kerning, line spacing and more.

  • Faking an API Server with URLProtocols

    #471

    Imagine you're building an app that will consume an API, however the API is not ready yet. The server team has given you some sample responses as JSON files you can use to start working against. In this episode we'll examine a useful technique of registering a custom URLProtocol for intercepting and handling network requests. We can use this fake server to continue building out our network infrastructure without being dependent on the backend API.

  • Working with Measurements in Swift

    #462

    Foundation has a wonderfully useful support for dealing with measurements like distances, durations, temperatures and more in Swift. The Measurement class combines with a Unit type to constrain the measurements into their own domains. With this you can get functionality like conversion and addition. With MeasurementFormatter we can format these values for display in our UI based on the user's locale. In this episode we will explore how to use this API, how to extend the existing dimensions to add new measurement values, and how to create your own domain of measurements. For this we will model Throughput of Items in the game Factorio.
