Xcode 6 MyPlayground

Xcode 6 有個新玩意MyPlayground

好奇寶寶來試試看XDDDD

好像滿好玩的

變數形態用var   

沒有用分號(;)做程式的結尾～

寫程式真開心～哈哈哈哈哈

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

import UIKit

var str = "Hello, playground"

var msg = "Hello World!"

var x = 2

var y = 3

var z = 4

var sum = x + y + z

println(msg)

println(sum)

if( sum >= 10 )

{

    println("sum >= 10")

}

else

{

    println("sum < 10")

}
