Reducing the number of brackets in Swift

In swift you have to add braces even if there is just one statement in if:

if num == 0 {
  // Do something
}

You cannot leave the braces, that how swift if statement work.

You can do that :

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

And so much interesting things :

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()

Edit : ternary operators and compilation

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