debugDescription

TypeScript

get debugDescription(): string

Swift declaration

var debugDescription: String { get }

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