swift core data crash after adding attributes to an entity

I have an entity in my data model, after I added an additional entity the app crashes when i try to acces it.

var request = NSFetchRequest(entityName: "Entity");
var results=context.executeFetchRequest(request, error: nil);

Even if there is no items stored in it, it still crashes. If i delete the app and try again it does not crash.

Crash message : "reason = "The model used to open the store is incompatible with the one used to create the store""

Every time you change the database model you must reset the iOS simulator as it has an old version of the database.
