guard let unwrappedValue = optionalValue else {
    // Code to execute if optionalValue is nil
    // Usually, you would use return or throw to exit the current scope
    // e.g., return, throw, break, continue, etc.
}
// Code to execute if optionalValue is not nil, and unwrappedValue is available for use
