I downloaded and installed the Xcode 12 beta and now want to test on an iOS 14 simulator, but the iOS 14 simulator is not installed and can't be found in Preferences/Components to download. What am I missing?

I have recently implemented the strong password suggestion by using a textfield in the vc with textField.textContentType = .newPassword. a) It works fine on most of my test devices, but does not suggest a password on a few. b) There is one device (iPhone 8, iOS 14.0) that does indeed suggest a password, but shows the keyboard so slow that it appears like a bug (keyboard appears with grey background only for several seconds), only then changes to the keyboard later. When using the strong password (and I assume therefore saving it) the device / actions still are dragging on. It's not so bad that the password is not suggested on a few, but I still would be interested what the difference is to the working ones. I can't release the app though with the second issue where the phone slows down. I am very thankful for any suggestion on how to further test and proceed with this.
