// This is an example of the Tuple type in Swift programming language 
// I use this type of data to easily return multiple values from a function call
// SEE: https://docs.swift.org/swift-book/LanguageGuide/TheBasics.html#ID329

let t = (200, "OK", "HTTP 200 is a successful return code. The request has succeeded.")

print(t)    // shows the entire tuple
print(t.0)  // shows 200
print(t.1)  // shows "OK" 
print(t.2)  // shows the longer message
print(t.3)  // will be an error

let (a,b,c) = t // destructures the tuple into 3 separate variables 
print(a)  // shows 200
print(b)  // shows "OK"
print(c)  // shows the longer message
