@MainActor @preconcurrency protocol TableRowContent<TableRowValue>

A type used to represent table rows. Like with the ``View`` protocol, you can create custom table row content by declaring a type that conforms to the `TableRowContent` protocol and implementing the required ``TableRowContent/tableRowBody-swift.property`` property. struct GroupOfPeopleRows: TableRowContent { @Binding var people: [Person] var tableRowBody: some TableRowContent<Person> { ForEach(people) { person in TableRow(person) .itemProvider { person.itemProvider } } .dropDestination(for: Person.self) { destination, newPeople in people.insert(contentsOf: newPeople, at: destination) } } } This example uses an opaque result type and specifies that the primary associated type `TableRowValue` for the `tableRowBody` property is a `Person`. From this, SwiftUI can infer `TableRowValue` for the `GroupOfPeopleRows` structure is also `Person`. A type conforming to this protocol inherits `@preconcurrency @MainActor` isolation from the protocol if the conformance is included in the type's base declaration: struct MyCustomType: Transition { // `@preconcurrency @MainActor` isolation by default } Isolation to the main actor is the default, but it's not required. Declare the conformance in an extension to opt out of main actor isolation: extension MyCustomType: Transition { // `nonisolated` by default }
