减少Swift中的括号数

有人知道有没有办法使用某种速记的速记？更具体地说,在诸如IF语句之类的东西中省略大括号

if num == 0
  // Do something

代替

if num == 0
{
  // Do something
}

当你有几个嵌套的IF,这些大括号变得相当空间消耗.

PS.我知道我可以做以下事情：

if num == 0 {
  // Do something }

但是,如果有可能的话,我仍然很好奇

你可以这样做：

let x = 10,y = 20;
let max = (x < y) ? y : x ; // So max = 20

还有这么多有趣的事情：

let max = (x < y) ? "y is greater than x" : "x is greater than y" // max = "y is greater than x"
let max = (x < y) ? true : false // max = true
let max = (x > y) ? func() : anotherFunc() // max = anotherFunc()
(x < y) ? func() : anotherFunc() // code is running func()

编辑：注意三元运算符

By doing nothing more than replacing the ternary operator with an if else statement,the build time was reduced by 92.9%.
