 |`appium:safariLogAllCommunicationHexDump`|Log all communication sent to and received from the Web Inspector, as raw hex dump and printable characters. This logging is done _before_ any data manipulation, and so can elucidate some communication issues. Like `appium:safariLogAllCommunication`, this can produce a lot of data in some cases, so it is recommended to be used only when necessary. Defaults to `false`.|`true` or `false`|
 |`appium:safariSocketChunkSize`|The size, in _bytes_, of the data to be sent to the Web Inspector on iOS 11+ real devices. Some devices hang when sending large amounts of data to the Web Inspector, and breaking them into smaller parts can be helpful in those cases. Defaults to `16384` (also the maximum possible)|e.g., `1000`|
 |`appium:safariWebInspectorMaxFrameLength`| The maximum size in bytes of a single data frame for the Web Inspector. Too high values could introduce slowness and/or memory leaks. Too low values could introduce possible buffer overflow exceptions. Defaults to 20MB (`20*1024*1024`) |e.g. `1024`, `100*1024*1024` |
-|`appium:additionalWebviewBundleIds`|Array (or JSON array) of possible bundle identifiers for webviews. This is sometimes necessary if the Web Inspector is found to be returning a modified bundle identifier for the app. Defaults to `[]`|e.g., `['io.appium.modifiedId', 'ABCDEF']`|
+|`appium:additionalWebviewBundleIds`|Array (or JSON array) of possible bundle identifiers for webviews. This is sometimes necessary if the Web Inspector is found to be returning a modified bundle identifier for the app. If the value includes `*`, XCUITest driver will return all available webview contexts on the device. Defaults to `[]`|e.g., `["io.appium.modifiedId', 'ABCDEF"]`, `["*"]`|
 |`appium:webviewConnectTimeout`|The time to wait, in `ms`, for the initial presence of webviews in MobileSafari or hybrid apps. Defaults to `0`|e.g., '5000'|
 |`appium:safariIgnoreWebHostnames`| Provide a list of hostnames (comma-separated) that the Safari automation tools should ignore. This is to provide a workaround to prevent a webkit bug where the web context is unintentionally changed to a 3rd party website and the test gets stuck. The common culprits are search engines (yahoo, bing, google) and `about:blank` |e.g. `'www.yahoo.com, www.bing.com, www.google.com, about:blank'`|
 |`appium:nativeWebTap`| Enable native, non-javascript-based taps being in web context mode. Defaults to `false`. Warning: sometimes the preciseness of native taps could be broken, because there is no reliable way to map web element coordinates to native ones. | `true` |
