Usando SwiftUI con Core Data

Solución:

La lista no requiere Array. los Data debe ajustarse a la RandomAccessCollection protocolo. Este también podría ser tu NSFetchedResultsController.

extension List {
    /// Creates a List that computes its rows on demand from an underlying
    /// collection of identified data.
    @available(watchOS, unavailable)
    public init<Data, RowContent>(
        _: Data,
        selection _: Binding<Selection>?,
        rowContent _: @escaping (Data.Element.IdentifiedValue) -> RowContent
    ) where Content == ForEach<Data, HStack<RowContent>>,
        Data: RandomAccessCollection,
        RowContent: View,
        Data.Element:
        Identifiable

    /// Creates a List that computes its rows on demand from an underlying
    /// collection of identified data.
    @available(watchOS, unavailable)
    public init<Data, RowContent>(
        _: Data,
        selection _: Binding<Selection>?,
        action _: @escaping (Data.Element.IdentifiedValue) -> Void,
        rowContent _: @escaping (Data.Element.IdentifiedValue) -> RowContent
    ) where Content == ForEach<Data, Button<HStack<RowContent>>>,
        Data: RandomAccessCollection,
        RowContent: View, Dat
}
