Logical Operators: Or (||) in Swift

Sometimes we will need to run some code if at least one of two conditions is true. The logical or operator (||) returns true if either of the conditions is true. Otherwise, if both conditions are false, it returns false.
For example:

7 >= 10 || 10 < 12 // Evaluates to true

We have two conditions separated by || operator:

• 7 >= 10, which evaluates to false
• 10 < 12, which evaluates to true

Another example:

10 < 15 || 10 > 9 // Evaluates to true as both conditions are true

An example inside an if statement:

let x = 10
if x != 10 || 12 < x { // Evaluates to false
    print("This is true!")
}

Both conditions evalute to false, so the entire condition evaluates to false and the program prints nothing.
