I tried my implementation in Xcode 12.1 GM and this issue still exists. I can find there are two picker wheels but the error throws when I try to adjust them.

I was rewriting the automation code. /* Find the new date picker row and tap to enter new calendar view */ let compactDatePicker = self.app.descendants(matching: .any)["Date Picker"] compactDatePicker.tap() /* Tap top left "September 2020" button to enter month and date selection view */ self.app.buttons["Show year picker"].tap() /* Unsupported picker wheel error throws here */ self.app.pickerWheels.element(boundBy: 1).adjust(toPickerWheelValue: "2020") After it enters the month and year view, it becomes a pickerWheel view. I searched elements in debugger console, it is also shown as a pickerWheel but I cannot adjust it. I also tried this implementation in Xcode 12.0.1 and the issue still exists. I am just wondering whether this is a bug in Xcode 12 or there is another solution to adjust this type 6 pickerWheel.

The problem still exists for UICollectionView now. All the crashing devices are iOS 13 and iOS 14.0. Has anyone found what the problem is?
