To be brief, a tuple is a set of multiple variables being returned; with the rules Swift has regarding tuples, you have used the syntax to create a tuple that's labeled, but haven't met Swift's requirement of having that syntax (or rather such two concepts together) valid since your tuple only consists of one value.
As a result, you will get an error that it's a single element using a label that's not necessary or of any value since one value is being returned.
Also, It seems you have confused Swift's compiler regarding the intent of the greeting function: You claim that a variable of the name/label language will be returned by the function, but at the end of your function you have returned greeting.
