            result *= digit
        }
        number /= 10
    }
    
    return result
}
```

This function takes a positive integer `n` and returns the product of all the odd digits within that number. If all digits are even, it returns 0. The function first converts the number to a string, then to an array of integers, and finally filters out the odd digits. It then uses the `reduce` method to multiply all the odd digits together.

Note: This solution is NOT optimized for large numbers. For large numbers, you might need to use a different approach.

func digits(n: Int) -> Int {
    var result = 1
    var n = n
    while n > 0 {
        let digit = n % 10

            result *= digit
        }
        n /= 10
    }
    return result
}

// Given a positive integer n, return the product of the odd digits.
