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.

setAttributes

TypeScript

setAttributes(attributes: AttributeContainer): void

Swift declaration

mutating func setAttributes(_ attributes: AttributeContainer)

subscript · iOS 26.0+

subscript

TypeScript

subscript(bounds: SDKHandle): DiscontiguousAttributedSubstring

Swift declaration

subscript(bounds: RangeSet<AttributedString.Index>) -> DiscontiguousAttributedSubstring { get }
