Same issue here. All my custom views are now showing Designables: Build Failed.

If clicked on Show or hover over the error it just says: Last updated some minutes ago.

Got the same problem on Xcode 12.4 and 12.2.
Just filed a bug report : FB9038195

BUT
  • I opened the project with Xcode 11.3.

  • Works Ok.

  • Closed it

  • Reopened in Xcode 12.4

  • IBDesignable shows without issue…
