Context about how a document was created.
SwiftUI passes this to the `makeDocument` closure of
``DocumentGroup``. Use ``creationSource`` to determine which
``NewDocumentButton`` the person tapped and configure the
document accordingly:
DocumentGroup { document in
EditorView(document: document)
} makeDocument: { configuration, context in
let document = NotesDocument()
if context.creationSource == .checklist {
document.template = .checklist
}
return document
}

description
TypeScript
get description(): string
Swift declaration
var description: String { get }
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the `String(describing:)`
initializer. This initializer works with any type, and uses the custom
`description` property for types that conform to
`CustomStringConvertible`:
struct Point: CustomStringConvertible {
let x: Int, y: Int
var description: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"
The conversion of `p` to a string in the assignment to `s` uses the
`Point` type's `description` property.

creationSource
TypeScript
get creationSource(): (DocumentCreationSource) | null
Swift declaration
var creationSource: DocumentCreationSource? { get }
The source associated with the button that created this document.
On iOS, you can specify the source using a ``NewDocumentButton`` in
``DocumentGroupLaunchScene``. On macOS, this is always `nil`.
