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 'swift-data'   Clear search
  • Migrating between versions of your model


    Leveraging SwiftData for Persistence

    In this episode we cover migrating our Swift Data models between incompatible versions using custom and lightweight migration.

  • Querying data with the @Query Macro


    Leveraging SwiftData for Persistence

    In this episode we will provide a searchable interface using the @Query and #Predicate macros. We'll discuss how to use localizedStandardCompare instead of lowercase and other limitations of predicates. We'll also implement a solution for adding dynamic data to the query.

  • Editing Relationships with SwiftData


    Leveraging SwiftData for Persistence

    In this episode we'll create a form to add and edit songs for a given artist. This will lean on the technique we used last time with a small workaround required.

  • Building forms to create and edit models with SwiftData


    Leveraging SwiftData for Persistence

    We learn how to build a form in SwiftData. We cover how to use the .sheet modifier to present a new view for creating or editing artist records. We also cover creating the state for the form, presenting the sheet, and creating the form itself. We also implement a scratch model context to ensure that our changes can be discarded if the user taps the Cancel button.

  • Inserting and Deleting records with the ModelContext


    Leveraging SwiftData for Persistence

    This episode discusses how to work with the ModelContext in a SwiftUI app to insert and delete data. The ModelContext can be accessed through the ModelContainer, which is set up in the environment automatically. The @Query macro is used to retrieve artists from the database and iterate over them. We also implement swipe to delete using the onDelete modifier.

  • The @Model Macro


    Leveraging SwiftData for Persistence

    In this episode we will take a look at the new @Model macro, which we can use to decorate our model classes that we want to persist with SwiftData.

  • SwiftData - The Basics


    Leveraging SwiftData for Persistence

    SwiftData is a replacement for CoreData, built entirely for Swift. It leverages the underpinnings of Core Data, but is much simpler to work with. In this video we will cover the first 3 main types you'll need to understand: ModelConfiguration, ModelContainer, and ModelContext.
