title: Core data many-to-many relationship - Predicate question
body: <p>In my Core Data model I have two entities: List and Patient. List has an attribute called 'name'.</p>
  
  <p>A List can have any number of Patients and each Patient can belong to any number of different lists. I have therefore set a relationship on List called 'patients' that has an inverse to-many relationship to Patient AND a relationship on Patient called 'lists' that has a to-many relationship to List.</p>
  
  <p>What I'm struggling to figure out is how to create a Predicate that will select all Patients that belong to a particular List name.</p>
  
  <p>How would I go about this? I have never used relationships before in Core Data.</p>
