iOS Swift Functions and Optionals Parameters and Tuples Decomposing a Tuple

Why using 2x "found"?

I am confused by using "Found" in two different ways.

within the function "found" ist used to store the whole tuple, i.e. either (true, "(name) ist a Treehouse Teacher") or (false, "(name) ist not a Treehouse Teacher")

outside the function, however, "found" is to be used as only the boolean value of the tuple.

For me that is highly confusing why to use the same variable name for two different things. Or am I missing a point here?

No, in fact you hit the nail on the head. In practice, you would want the local variable in searchNames to be something like "foundName". And then when applying labels, you'd want it to read like (isFound: Bool, description: String).
