Swift: How to filter in Core Data

Question

I\'m using the following code to fetch all the data in \"category\".

let appDelegate = UIApplication.sharedApplication().delegate as AppDelegate

let managedCon         


        

Answer 1

You can use .filter on the fetchedResults.

Answer 2

To "filter" results in Core Data, use NSPredicate like so:

let filter = "products"
let predicate = NSPredicate(format: "type = %@", filter)
fetchRequest.predicate = predicate
