I just upgraded my Xcode to 15.2 today. When it tries to download the list of available simulators, the request to fetch the list failed. From the error log, it says that this link is not returning the expected data: https://devimages-cdn.apple.com/downloads/xcode/simulators/index2.dvtdownloadableindex. It appears that this link is not returning any data at the moment.

It seems fixed now.
I tried to download the iOS 15 version, but it was an empty file.
