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 8 episodes with tag 'beta'   Clear search

    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.

    With the introduction of LazyVGrid and LazyHGrid In iOS 14 we now have access to much more powerful grid-based layouts in SwiftUI. In this episode We will examine the different types of layouts we can accomplish with flexible, fixed, and adaptive sizing for our rows and columns. We'll look at how animations work between different layouts, and how to consider larger screen sizes.

  • #444

    A few episodes back we covered how to wrap a UIActivityIndicatorView to show loading progress in SwiftUI. Now in iOS 14 this is built in. In this episode we'll cover the various styles, how to hook it up to a Progress instance, and how to create your own custom progress visualizations.

  • #443

    iOS 14 Beta is now available and one of the new features is Lazy stacks. With a normal stack, all the layout happened at once, which meant poor performance for large lists of content, grids, etc. With Lazy stacks the views are only created when they first come on screen, greatly increasing the usefulness of stacks for large or infinite collections of content.

  • #400

    Attaching gestures works quite a bit differently in SwiftUI than in UIKit. In this episode we will look at the @DragGesture property wrapper and how we can use gestures to update custom state that we can then use to transform our UI.

  • #399

    SwiftUI's declarative nature makes building UIs incredibly easy. In this episode we will build a wallet UI with cards. We will create a CardView so we can reuse it in multiple places. Then we will use transforms to alter it's size and position. Finally we will see how declarative animations work as we expand the cards apart.

  • #397

    Now that we've seen a taste of SwiftUI, let's dive into a real example and build an app. We'll have a first look at @State variables we can use to creating a binding between our state and our UI, and we'll run into a few puzzling errors and see how we can coax Xcode into giving us the right error message.

  • #396

    Back from WWDC 19 and blown away by the announcements. There's a lot to cover, but we'll start by digging into the most exciting announcement: SwiftUI. This is going to change everything...
