I am having problems with a core data app. (swift4 xcode 9.2) I thought I would start a new project and copy some of the old files into it. I tried copying the main storyboard and got the following error 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle </var/containers/Bundle/Application/952AF94B-62FA-4AEC-8C94-1E881D52043D/AZ5.app> (loaded)
I closed the project and reopened it and got this message.
Interface Builder could not open the document Main.storyboard" because it does not exist.
I looked in the finder folder for the project in the autosave area and it does exist.
I also tried copying the core data model file as well with similar results.
The reason I am trying to build a new project is that the origional project was only showing a table for the first set of data added then displayed with fetchedResultsController. Adding aditional data and even restarting the app would not display all of the data.
