In iOS 18, a SwiftUI View is now on MainActor

We wrap up our introduction to SwiftData with the remaining CRUD operations and add, delete, and modify a meeting

The @Query macro allows us to fetch instances from SwiftData, sort them, and filter them.

We prepare sample data from our SwiftData model for use with SwiftUI previews.

We look at SwiftData relationships and the @Model macro

We create @Model classes like those we created in Core Data that are ready to use in SwiftData.

We customize the generated code to be more Swifty by handling Optionals, special types, NSSet, and inits.

We generate Swift code for our Core Data entities.

We continue to motivate SwiftData by looking at the XML persisted by a simple Core Data model

We look back at Storyboards and SwiftUI to motivate the move to SwiftData

We wrap up our exploration of limits and continuity for now by looking at examples of a jump discontinuity and a removable discontinuity. My apologies for the narration - I had a cold that made things challenging.

A function is continuous at a point, if the limit exists there and the limit equals the value of the function. That's (essentially) it!

We motivate and formally define what we mean by the limit of a function

We take last week's ancient exploration of circles and polygons and move to a more modern understanding of limits.
