and

The and keyword is the logical AND operator. It returns true when both operands are truthy and short-circuits: if the left operand is falsy, the right operand is not evaluated.

Syntax & Example​

if active and ready {
    print("go");
}

let canFly = hasWings and isLightweight;

Use Cases​

  • Combining two conditions that must both hold.
  • Short-circuiting past an expensive check when an earlier check fails.
  • Building compound Boolean expressions readably.
