I solved this by changing "Photo" entity's codegen to "manual/none", and then CMD + B to compile first. Then hit run, and the error was gone. FYI: "I got this error for core data models that i've created manually.And it got resolved by changing particular entity's 'Codegen' attribute to 'Manual/None' under Data Model Inspector." from StackOverflow

If this won't work, the last hope is to duplicate the project manually. It ain't gonna take long.
