Swift CoreDataModel Select

I would like to know how do I select only a specific table from my CoreData, for example I have 6 fields, and would like to do a select from only information from a single field, could anyone help me?

My current code:

let request = NSFetchRequest(entityName: "Person")

request.returnsObjectsAsFaults = false

request.predicate = NSPredicate(format: "wordEasy = %@", "wordEasy")

do{
    let results  = try context.executeFetchRequest(request)
    print(results)
}
