                  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 customdebugDescriptionproperty for types that conform toCustomDebugStringConvertible: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 pto a string in the assignment tosuses thePointtype’sdebugDescriptionproperty.DeclarationSwift var debugDescription: String { get }
