Hello... for some reason, XCode previews are no longer working for me. It was working fine a week ago, however, now no matter ho many times i reboot or restart my computer, the preview won't load. The preview is stuck on "loading Preview" no matter how long I wait. I ran the same files on swift playgrounds and the preview works fine there, but not on XCode. I ran both my project and a completely new, unedited project and both will not preview- so I know it is not a problem with my file. Also, the second I open the app the preview pauses. Either way, I don't think an app with only one file should take so long to build...
