How do I get Upsert to work in SwiftData?
I have a model:
@Model
class Address: Identifiable {
@Attribute(.unique)
var id: Int = 0
var number: String = ""
var street: String?
var city: String?
}
When I insert a duplicate record with the same data attributes (specifically overlapping id) and execute modelContext.save() I receive a EXC_BREAKPOINT.
let addressA = Address(id: 1, number: "2300", street: "E Main St", city: "Small Town" );
modelContext.insert(addressA)
try? modelContext.save()
let addressAv2 = Address(id: 1, number: "2300", street: "E Main St", city: "Small Town" );
modelContext.insert(addressAv2)
try? modelContext.save() // This fails
Is there a better way to handle updates?
