I just ran into the same problem. Here is how I solved it:

Renaming the model file alone is not enough, because it does not rename the reference to the current model version.

It turns out the model version is stored in a separate plist file. Simply open it in a text editor and change the old name to your new model file name.

File: YourNEWModelFile.xcdatamodeld/.xccurrentversion

  
     _XCCurrentVersionName
     YourModelFile.xcdatamodel  <-- Change this to YourNEWModelFile
  

Please note that you should only do this if you rename the model file during development. For migrating your data model to a new version, follow the Core Data docs.
