Environment Variables

This article describes environment variables that influence various XCUITest driver behaviors.

Variable Name	Description
APPIUM_PREFER_SYSTEM_UNZIP	Being set to either 0 or false makes the driver to use built-in Node.js unzipper rather than the system unzip utility. Mostly used for debugging purposes or troubleshooting as the system unzip utility is more performant in comparison to the built-in one.
APPIUM_XCUITEST_PREFER_DEVICECTL	Being set to true, 1 or true makes the driver to use the devicectl Xcode utility to fetch the list of available devices UDIDs instead of the built-in usbmuxd client. Might be useful for some scenarios where the latter is unable to detect connected devices. See PR #2194 for more details.
