init(_:id:children:selection:rowContent:)

Creates a hierarchical list that identifies its rows based on a key path to the identifier of the underlying data and allowing users to have exactly one row always selected.

Declaration

@MainActor @preconcurrency init<Data, ID, RowContent>(_ data: Binding<Data>, id: KeyPath<Data.Element, ID>, children: WritableKeyPath<Data.Element, Data?>, selection: Binding<SelectionValue>, @ViewBuilder rowContent: @escaping (Binding<Data.Element>) -> RowContent) where Content == OutlineGroup<Binding<Data>, ID, RowContent, RowContent, DisclosureGroup<RowContent, OutlineSubgroupChildren>>, Data : MutableCollection, Data : RandomAccessCollection, ID : Hashable, RowContent : View

Parameters

  • data:

    The data for populating the list.

  • id:

    The key path to the data model’s identifier.

  • children:

    A key path to a property whose non-nil value gives the children of data. A non-nil but empty value denotes a node capable of having children that is currently childless, such as an empty directory in a file system. On the other hand, if the property at the key path is nil, then data is treated as a leaf node in the tree, like a regular file in a file system.

  • selection:

    A binding to a non optional selected value.

  • rowContent:

    A view builder that creates the view for a single row of the list.
