Use Optional Ternary Operator in Swift
Written by Team Kodeco
The Optional Ternary Operator, also known as the ternary conditional operator, is a shorthand way of handling optionals in Swift. It allows you to concisely check if an optional has a value, and perform different actions based on whether it does or not.
Here’s an example of how to use the Optional Ternary Operator:
let optionalInt: Int? = 5
let result = optionalInt != nil ? optionalInt! : 0
print(result) // Output: 5
In this example, the Optional Ternary Operator checks if the optional optionalInt
has a value. If it does, it unwraps the optional and assigns the value to the constant result
. If the optional is nil
, it assigns the value of 0
to the constant result
.
Note that although this works, your code is usually more readable if you use optional binding or the nil-coalescing operator instead.
