So, apparently there is an xcrun invocation that handles this: xcrun simctl --set previews delete unavailable | all This correctly cleans up the folder without crashing the Previews.

Facing the same issue. I just finished updating to Xcode 13.2 from the App Store and now I can't compile my project. 13.2 RC was working fine - but, I deleted it thinking the App Store version would be the same. Apparently not. I'm now left with having to re-download Xcode 13.2 from releases, on a 4Mbit line. I.e., my work day is done before it has even began. I also need to explain the loss of the work day to my employer. Thanks Apple for: not testing your releases thinking that everybody around the world is on a 200Gbps FTTH line.

So, after trying out the releases section version, it now crashes when I attempt to build the project. I.e., I now have 3 versions of Xcode, same version number, same build number exhibiting the following behaviors: App Store version: SPM does not work Releases downloadable version: Crashes on build RC version: works 🤷‍♂️

Same thing here. It is quite amazing how Apple is utterly inconsiderate of small developers. It seems they've assumed that everyone is a big company with dozens of available devices at hand, at any time, with all iOS versions at the ready. Perhaps this is the same reason why Xcode is such a huge beast and that app uploads to the store often fail at low bandwidths. They probably also assume that everyone runs on a fiber optic line or is a Cupertino resident.
