@@ -22,3 +22,4 @@ The XCUITest driver supports the following element attributes:
 | `value` | Element's value. This is a complex attribute, whose calculation algorithm depends on the actual element type. Check [WebDriverAgent sources](https://github.com/appium/WebDriverAgent/blob/master/WebDriverAgentLib/Categories/XCUIElement%2BFBWebDriverAttributes.m) to know more about how it is compiled (method `- (NSString *)wdValue`). Could be `null` | `hello` |
 | `hittable` | Whether the element is [hittable](https://developer.apple.com/documentation/xctest/xcuielement/1500561-hittable). Note that XCTest hittable requires an element to have the [isAccessibilityElement](https://developer.apple.com/documentation/objectivec/nsobject-swift.class/isaccessibilityelement) property enabled. It means if the element is on screen, but it sets [accessibilityElementsHidden](https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityelementshidden) to `false`, the hittable attribute will be `false`. This attribute is not included into the XML page source due to performance reasons, although you can use it in element locators or fetch its value using [getAttribute](https://www.w3.org/TR/webdriver2/#get-element-attribute) API. | `true` |
 |`placeholderValue` | Element's [placeolderValue](https://developer.apple.com/documentation/xctest/xcuielementattributes/placeholdervalue) value. | `Placeholder text`|
+|`traits` | Element's [traits](https://developer.apple.com/documentation/uikit/uiaccessibilitytraits?language=objc) value. This attribute returns a comma-separated string of accessibility traits. This attribute is not included into the XML page source, it may only be retrieved via [getAttribute](https://www.w3.org/TR/webdriver2/#get-element-attribute) API.| `Button, Adjustable`, `Button` |
