closures.swift

//: Playground - noun: a place where people can play

import UIKit

func filterGreater(closure: (Int, Int) -> Bool, numbers: [Int], value: Int) -> [Int] {
    var filterNumbers = [Int]()
    for num in numbers {
        if closure(num, value) {
            filterNumbers.append(num)
        }
    }
    return filterNumbers
}

let listOfNumber = [1,2,3,4,5,6,7,8,9,10]
let filteredList = filterGreater(closure: { (number, value) -> Bool in
    return number > value
}, numbers: listOfNumber, value: 3)
print(filteredList) // return [4, 5, 6, 7, 8, 9, 10]
