or

The or keyword is the logical OR operator. It returns true when either operand is truthy and short-circuits: if the left operand is truthy, the right operand is not evaluated.

Syntax & Example​

if isWeekend or isHoliday {
    print("day off");
}

let hasAccess = isAdmin or isEditor;

Use Cases​

  • Combining conditions where any one being true is sufficient.
  • Short-circuiting past an expensive check when an earlier check succeeds.
  • Providing fallback conditions in validation logic.
