We compare SwiftData’s new features with SQLiteData, starting with a domain modeling exercise. We will rewrite the Trips @Model classes into simple @Table structs, and we will explore how the Draft type can power a single form for both creating and updating trips: www.pointfree.co/episodes/ep3...

The pattern Apple has established for influencing a view’s @State from a parent:
1. Make the state private and Optional
2. Populate the state in onAppear
This means extra boilerplate, imprecise domains, optional coalescing and chaining dances, and potential lifecycle bugs!

Xcode 27 beta 6 quietly changed how SwiftData's sectioning APIs work. Did you notice?
The @Query macro must now explicitly use the SectionedResults type, which means it is no longer possible to dynamically add/remove sectioning from a view.

There was an unexpected hubbub last week when we said lazy @State only works for private variables.
Well, we're back at it. We feel @State still doesn't adequately solve the problem of dynamically initialized state, so we are introducing @LazyState:

We explore the problems not solved by the new @State macro and explain why we think they should be solved. To close this gap we introduce a new @LazyState macro, which allows you to delay initialization of your state, all without introducing any new API!

You've probably heard by now that SwiftUI has a fancy @State macro that lazily creates state, fixing a longstanding issue in the framework.
But what you may not know is that the laziness only kicks in for **private** state.

The new @State macro uses a type called LazyState under the hood, and this type has secretly existed in SwiftUI for years!
We lift the veil on this type in this week's episode to see how Apple was able to back port @State to iOS 17:

The new @State macro fixes a long-standing bug in SwiftUI, that of objects being needlessly allocated. But have you looked at the expanded macro code yet? Looks like gobbledygook!
We show that all of this code is essentially just 3 lines of code:

WWDC26 brought the new @State macro to succeed the property wrapper, but what’s different about the macro, and how does it work? We’ll pick apart the cryptic macro expansions to see something quite simple at its core.

We built a geofence for our Trips app that turns red if it doesn’t contain the trip. Impressive stuff, but complex enough to deserve some tests!
We show how to exhaustively test it like a value type, so a missed assertion is a test failure with a nice message. 🤯

Many took SwiftData queries being limited to SwiftUI views as proof that everything belonged in views. But appleOS 27 now allows queries to live outside views, which is something SQLiteData has supported since day one and back-deploys to iOS 16!

We always felt SwiftData queries were needlessly constrained by having to live directly in views. That’s why SQLiteData was built from day one to work equally well in SwiftUI views, @Observable models, and even UIKit view controllers.
