Desciption: The UI tests work on the local machine (Mac mini), but not on the Xcode server. The Mac mini is also used for the Xcode server. For some integrations on the server, some UI tests work, but often they fail again for the next integrations. iOS simulators and devices were used when running the UI tests. The error usually happens when typing into a textfield. Some people suggested to modify the "setUp" and "tearDown" functions to this: override func setUp() {         XCUIApplication().terminate()         super.setUp() XCUIApplication().launch() } override func tearDown() { super.tearDown() XCUIApplication().terminate() } But that also didn't work. I don't understand why the UITests don't work on the server, but do work on the local machine without the server.
