问题 I am building an application that utilizes an MDM API to make bulk updates to attributes of devices. I am looking to have some sort of visible output/logging in the main view so that the user can see what lines of their CSV may have failed and what the HTTP Response Code was.

问题 In Xcode 8 / Swift 3, using the coordinate(withNormalizedOffset: CGVector) function to interact with an XCUIElement appears to work only in portrait mode. To test this functionality, I created a single screen project with a button centered in the view. I then ran the following UI test: func testExample() { XCUIDevice.shared().orientation = .portrait let window = XCUIApplication().windows.element(boundBy: 0) let centerPoint = window.coordinate(withNormalizedOffset: CGVector(dx: 0.5, dy: 0.5))
