How to join two strings for NSPredicate, ie firstname and lastname

Question

I have a Person Object which has two NSString properties; firstName and lastName. I\'m currently using an NSPredicate like so

Answer 1

The solution suggested above will not work with search strings that have more than two words. Here is a more thorough implementation in swift. This solution also allows for adding more fields on a record, if your goal is to implement a full text search across name, email, phone number, etc. In that case just update the NSPredicate to OR newField CONTAINS[cd] %@ and be sure to add the extra $0 in the list of string replacements.

let searchText = search.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
let words = searchText.componentsSeparatedByCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
let predicates = words.map { NSPredicate(format: "firstName CONTAINS[cd] %@ OR lastName CONTAINS[cd] %@", $0,$0) }

let request = NSFetchRequest()
request.predicate = NSCompoundPredicate(type: NSCompoundPredicateType.AndPredicateType, subpredicates: predicates)
