Answer 1

Check this out :

var customerNameDict = ["firstName":"karthi","LastName":"alagu","MiddleName":"prabhu"];
var clientNameDict = ["firstName":"Selva","LastName":"kumar","MiddleName":"m"];
var employeeNameDict = ["firstName":"karthi","LastName":"prabhu","MiddleName":"kp"];

var attributeValue = "karthi";

var arrNames:Array = [customerNameDict,clientNameDict,employeeNameDict];

var namePredicate = NSPredicate(format: "firstName like %@",attributeValue);

let filteredArray = arrNames.filter { namePredicate.evaluateWithObject($0) };
println("names = ,\(filteredArray)");
