Same for me. @Model macro doesn't seem to like settings default values, but Cloudkit requires it for non-optional values...

What do you mean by it will break, how so? (just interested because im facing some issues with the self._$backingData issue)

Glad to see they've updated the release notes. Wasn't there when i looked earlier yesterday

Indeed this shouldn't be the workaround, as this will force you to make all items optional
