Swift - Conditional or Ternary operator (?:)
The Swift conditional or ternary operator returns one of the two values based on the value of boolean expression. It is kind of similar to the if-else statement and helps to write the if-else statements in a short way.
Syntax
//returns value1 if expression is true //returns value2 if expression is false expression ? value1 : value2
Return Value
Returns value1 if the expression is evaluated to be true, and value2 if the expression is evaluated to be false.
Example:
In the example below, the ternary operator is used to find out the maximum of two numbers.
var x = 50 var y = 100 //maximum of two value var max = (x > y) ? x : y //displaying the result print("Maximum value = \(max)")
The output of the above code will be:
Maximum value = 100
