title: Saving an NSMutableArray to Core Data
body: <p>I want to add an NSMutableArray of NSStrings to one of my Entities in my core data model.  The problem is that this isn't a supported type in Core Data.  </p>
  
  <p>I tried making a tranformable attribute, but the problem is that I see no way of turning a NSMutableArray to NSData, and then going from NSData, back to an NSMutableArray.  Does anyone have an idea as to how this issue can be solved? </p>
  
  <p>(I know I can archive the array, but I don't want to do that, I want it to be present in my model).</p>
