Hello, I cannot set a variable "Result" equal to one of two elements in a tuple.

I've been struggling to get this simple result back. I cannot seem to decompose one of two tuple elements to the variable result.

You can access both values using dot notation and it's index

// The tuple
let error = (404, "Page not found")

// Access the first value with .0
let errorInt = error.0

// Access the second value .1
let errorDescription = error.1

The index always starts on a 0, just like an array.

Hope this helps.
