swift闭包学习

闭包作为参数

func getList(score:[Int],con:(Int)->Bool) -> [Int]
{
    var newScore:[Int] = [Int]()
    for item in score
    {
        if con(item)
        {
            newScore.append(item)
        }
    }
 return newScore
}

//let newArray = getList(score: [75,60,95,45,85] ,con:{ (s:Int) -> Bool in
//    return s>80
//})

let newArray = getList(score: [75,60,95,45,85],  con:{$0>80})
print(newArray)
