The compiler only knows about methods declared somewhere or the

One solution is to use [managedObject valueForKey:@"memo"] and
[managedObject setValue:@"test123" forKey:@"memo"] instead of the
accessors.
No, don't do this.
If you don't want to define a custom managed object class, the correct
solution is to add a category of NSManagedObject that defines the
methods to keep the compiler happy.

Substituting KVC methods just to suppress compiler warnings needlessly
makes your application less efficient.
