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. 👌
#518
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
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
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
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
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
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
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
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
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
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
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.
#361
We continue building out our little promise library, this time adding an ensure method, refactoring how we call the callback blocks, and fix a race condition issue by triggering callbacks even if the value has already been provided.
#360
Promises are a useful way of turning async code and writing it as if it were synchronous. In this episode we'll create a promise library from scratch so we can see how they work under the hood.
