Multiple NSPredicates for NSFetchRequest in Swift?

You can use “NSCompoundPredicate”. For example:

let converstationKeyPredicate = NSPredicate(format: "conversationKey = %@", conversationKey)
let messageKeyPredicate = NSPredicate(format: "messageKey = %@", messageKey)
let andPredicate = NSCompoundPredicate(type: NSCompoundPredicateType.AndPredicateType, subpredicates: [converstationKeyPredicate, messageKeyPredicate])
request.predicate = andPredicate

You can change into “AndPredicateType” or “OrPredicateType”
