I want to install an older simulator runtime with command line using xcodebuild, following instructions from this article: https://developer.apple.com/documentation/xcode/installing-additional-simulator-runtimes As of October 2024, this article provides an example: xcodebuild -downloadPlatform iOS -buildVersion 16.0 -exportPath ./SimulatorRuntimes/ However when I run this command in the terminal, it fails with error: xcodebuild: error: invalid option '-buildVersion' Has this option been removed? What's the correct way to install an arbitrary non-latest simulator runtime with command line? I know I can download the runtime from the website and then import it, or I can use Xcode's GUI for that, but my eventual goal is to automate it with a single shell script. I'm using Xcode 16.0 (16A242d) on macOS Sequoia 15.0.1. Thanks in advance for your help!

I have an app at work that supports Sign In With Apple so that users can create accounts and have their data synced to servers. A couple of years ago one of the users created an account using Sign In With Apple, choosing to use Hide My Email as well (so that their email that the app received looks like *****@privaterelay.appleid.com). The legacy in-house backend of the app unfortunately uses email addresses as user identifiers with the unlucky assumption that emails remain the same. The app doesn't offer users the ability to change email addresses. The user in question recently reported that since very recently they are no longer able to use the app. It turns out that their Sign In With Apple email address for my app had changed at some point. They shared an iPhone screenshot of their Sign In With Apple settings for the app. The screenshot says that they created an account for this app two years ago, but the email address in the "This app received" field is different to one that they initially signed up with, and it's also a Hide My Email address. It's important to note that this app was also transferred between developer accounts about a year ago, and since then this user, including thousands of other users didn't have issues using Sign In With Apple. So my main question is: in what scenario it's possible for the email associated with a Sign In With Apple account for an app to change without creating a new account?
