Ternary Operator in Swift
The ternary operator is used to execute code based on the result of a binary condition.
It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a method.
result = binaryCondition ? valueReturnedIfTrue : valueReturnedIfFalse;
The ternary is strictly an assignment operator (cannot be used to execute expressions).
let num1 = 3 let num2 = 5 var max = num1 > num2 ? num1 : num2
