@bob39722 For me this didn't work. For [NSInteger] I still receive CoreData: Declared Objective-C type "[NSInteger]" for attribute ... is not valid when using NSSecureUnarchiveFromData.

@ptxmac, the preview works with this workaround, but I can not import the Library anymore. I always get the error "No such module ...".

I can confirm this, 13.3 increased build time for at least +33%.
