I noticed that XCTest(UI) required us to input passcode to run on a real device if the device has had a passcode security preference on iOS 15. The passcode can be fingerprint or face id. (It depends on its preference)
It means Appium/WDA also gets the same issue. It should not be an impact on a device that does not have a passcode.
So far, the passcode step appeared only after rebooting the device. I don’t know of the passcode step appears after a while without rebooting the device.
