# subscript(dynamicMember:) Returns the intent’s output, converted to the inferred type. ``` subscript(dynamicMember keyPath: KeyPath) -> T where T : IntentValueConvertible { get throws } ``` ## Overview Access the return value using the `value` key path, for example: ```swift let result = try await intent.run() // Compare the result with a concrete value. XCTAssertEqual(try result.value, "Hello World") ``` If the property’s value isn’t an instance of the type `T`, this subscript throws an error.
