the struct – Meaning they belong to ContentView, rather then just being free-floating variables in our plan.

SwiftUI can make it straightforward to start out applying SwiftData with just a single line of code. Data modeled with @Model is noticed by SwiftUI quickly. @Question competently fetches filtered and sorted details for your personal sights and refreshes in reaction to alterations.
