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. 👌

There are 15 episodes with tag 'networking'   Clear search
  • #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.

  • #463

    Pigeon is an interesting and powerful library for SwiftUI and UIKit for fetching and caching data. In this episode we will explore the library and how we can use it to build a simple Star Wars Universe explorer app using the Star Wars Dev API.

  • #433

    With SwiftUI views we no longer have view controllers, and this can pose the question: Where does our data access and networking code live? In this episode we will load some data from a movies API in order to examine the ObservableObject protocol.

  • #390

    Making a Podcast App From Scratch

    To get the information we need for the Podcast Detail screen, we’ll have to get the feed URL and parse it. There’s no built-in Codable support for XML, so we’ll look at using FeedKit to parse the feeds and extract the relevant information we need.

  • #389

    Making a Podcast App From Scratch

    In this episode we build another API client to search for podcasts matching a term and customize the UI and behavior of the search bar. We display the recommended podcasts first, then when a user types in a term we show the matching podcasts from the iTunes API.

  • #387

    Making a Podcast App From Scratch

    It's time to start talking to external APIs to get the data we want to display in the app. We start by exploring the API we want to consume with Paw, a useful macOS app. We then create a simple API client class that abstracts most of the boilerplate logic around how to handle the various URLSession outcomes.

  • #335

    Testing iOS Applications

    In this episode we implement OHHTTPStubs, a library that can be used to intercept and stub out network calls made with URLSession. Using this technique we can avoid hitting the network for our tests. We can also simulate different responses that are difficult or impractical to simulate in a real request.

  • #334

    Testing iOS Applications

    In this episode we talk about testing requests against a real API. For this we will build an app called CoinList that leverages the Crypto Compare API to fetch stats about crypto currencies.

  • #241

    Large File Downloads

    In this episode we take the download state and progress notifications and update the user interface to reflect this state. We'll see how to translate the notification into the indexPath for that episode row, and how to fake a change related to the fetched results controller to trigger a reload of the content. We will leverage the RateLimit library to save periodic changes in progress to the model without overwhelming Core Data.

  • #240

    Large File Downloads

    In this episode we create a DownloadInfo model in CoreData in order to track the state of a download, separate from any view controller.

  • #239

    Large File Downloads

    Downloading large files on iOS represents some unique challenges. Downloads should occur in the background, not confined to a particular view controller. They should be able to report progress on multiple screens, and should be robust enough to survive application suspension and failing network conditions, and respect the user's cellular data plan. In this episode we start a series on downloading large files that will cover all of the above concerns.

  • #204

    In this episode we start writing an application-specific API Client. We use Argo to decode our JSON response into an Episode model, including some nested object decoding, date formatting, and wrap it up by testing the implementation to make sure it works.

  • #203

    In this episode I start creating a reusable api client that will make it a lot easier to consume a JSON api and convert the response into model objects. It uses Argo for the JSON parsing, and leverages Swift features to provide a rich callback for the API calls.

  • #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.

  • #89

    In this episode we take a look at the brand new NSURLSession family of classes. We'll consume the iTunes Affiliate Search API and show how to do a simple GET request.
