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. 👌

    Sometimes we run into issues where SwiftUI doesn't quite do what we need. In some cases, SwiftUI views are powered by UIKit under the hood. Wouldn't it be great (and devious) to dig into the underlying UIKit views to customize things when vanilla SwiftUI just won't cut it? In this episode we'll look at a technique for discovering the UIKit underneath SwiftUI views.

  • #530

    In this episode we will examine FocusedValue and FocusedBinding, which are property wrappers that allow you to react to some state when a nearby field gets focused.

  • #529

    There are a number of types, propertyWrappers and view modifiers describing "focus" so it is not immediately obvious what they are all for. In this episode we will see how we can control focus for a text field in SwiftUI. We'll see how to use simple Bools as well as your own types to describe which field has focus. Finally we'll touch on a common request that doesn't yet have a great answer: setting focus in onAppear.

  • #528

    In iOS 15 we can take advantage of the long-awaited OSLogStore, which allows you to capture and filter logs for your process on device. In this episode we will examine the NSScreencast application, which utilizes logging pretty extensively. We will build a rudimentary debug shake menu to show recent logs.

  • #527

    iOS 14 brought some nice improvements to os_log via a new type called Logger. This leverages Swift's StringInterpolation type to make it much more usable for formatting values inside your logs. It does this without sacrificing the privacy and performance that makes os_log so appealing. In this episode we will see how we can adopt this new API as well as how StringInterpolation works under the hood.

  • #526

    One of the most impactful things you can do to improve productivity is to improve turnaround time when iterating on features. Playgrounds and Xcode Live Previews are great, but both have their limitations. In this episode we will explore how to utilize hot module reloading to have the simulator automatically reflect your changes when you save. It's magic, and will blow your mind!

  • #525

    Building a Wordle Clone in SwiftUI

    We now have all the pieces in place to make this game playable. We'll choose a random word, and then move on to detecting won/lost games and provide the ability to restart and keep playing.

  • #524

    Building a Wordle Clone in SwiftUI

    In this episode we create a custom transition using a GeometryEffect to add a nice flip animation for the letters as they are revealed.

  • #523

    Building a Wordle Clone in SwiftUI

    Now that we have some information associated with each of our typed characters, we can use that to color each letter according to its status.

  • #522

    Building a Wordle Clone in SwiftUI

    This time we'll focus on moving on from a simple string to a data structure that can capture the status of each guessed letter.

  • #521

    Building a Wordle Clone in SwiftUI

    In this episode we will handle the enter key and migrate our state to contain an array of guesses. We will then refactor to an observable object to better encapsulate state changes and to enable testability.

  • #520

    Building a Wordle Clone in SwiftUI

    Let's make the letters bounce a little as they are being typed. To do this we'll have to see how animated state changes are performed and how we can restructure our view hierarchy to achieve the results we're after.

  • #519

    Building a Wordle Clone in SwiftUI

    In this episode we'll design a letter grid and build up text input using a hidden textfield, displaying the typed letters in our own UI.

  • #518

    Async / Await

    In this episode we create an image cache using an actor that provides disk-caching for images from the Unsplash API. We'll also talk about Sendable and enable some compiler warnings to help us catch potential issues.

  • #517

    Async / Await

    In this episode we will look at two ways of generating async values with AsyncStream. We'll examine the difference between the push and pull models and how to deal with back pressure.

  • #516

    Async / Await

    We explore how we might encapsulate logic within an AsyncSequence and introduce the need for a type erased version. Type-erasure has some pros and cons and in this video we will explore how to create one called AnyAsyncSequence and how we can use it.

  • #515

    Async / Await

    In this episode we will see how to create and use our own AsyncSequence, which allow us to iterate over values that can arrive asynchronously. We'll see how this compares to traditional sequences and how to make use of AsyncIterator to build our own AsyncSequence implementations.

  • #514

    Async / Await

    The unit of work in Swift Concurrency is the Task. In this episode we will see how tasks are created and structured, how to run work in parallel, and how to handle cancellation by aborting work or returning partial results.

  • #513

    Async / Await

    Actors are a new first class concept in swift. In this episode we will explore the problem they solve and how to use them to avoid race conditions which can lead to inconsistent results or even crashes.

  • #512

    Async / Await

    Continuations are great for adapting completion-handler APIs to the new async await world. But what about delegate callbacks, which happen in an entirely separate method? In this episode we will adapt 2 delegate APIs into async await to see how this works.

  • #511

    Async / Await

    With Continuations we can bridge the non-async world and make it async. Continuations allow us to take the result of a completion block and turn it into an async flow. In this episode we will see the difference between checked and unchecked continuations as well as their throwing variants.

  • #510

    Async / Await

    In this episode we will see how URLSession can be used with async await. With this new API you can easily send network request and await a tuple of both the data and the response object.

  • #509

    Async / Await

    In this episode we will see how we can run tasks concurrently with concurrent for loops, which is useful when the number of items you want to process is dynamic. With Task Groups you can process results asynchronously and assemble the results in a safe way.

  • #508

    Async / Await

    In this episode we will show how the async await keyword can simplify asynchronous code, reading top-down as if it were synchronous, but without blocking any threads. We'll also see how async let can allow you to process multiple values concurrently.
