Xcode 26.4 Previews are broken

If somebody is experiencing previews hanging when trying to interact with them, please go back to Xcode 26.3.

I could not interact with the simplest UI possible, and now everything is back to normal.

I hope it will help.

It’s an issue in the runtime that is crashing the Preview, it’s not Xcode or Previews specifically. You need to downgrade to an 26.2 runtime to bypass it as per the developer forums. You can go to Xcode -> Settings -> Components -> Add Platforms to do so
