Return issues in Swift

Question

This doesn't work for me, all kinds of weird things happening. I have:
Swift
func fullName(firstName: String, lastName: String) -> String {
     return firstName + lastName
}

When I call this with fullName I get this weirdness.
Swift
fullName(firstName: String, lastName: String)

Except firstName: String are editable and only String for the second part is??? What is going on.
I should be able to have this:
``` Swift
func fullName(firstName: String, lastName: String) -> String {
     return firstName + lastName
}
print(fullName("Phil","Hanson"))
```
But this doesn't work.

Hi Phil,
All methods called on an object use parameter names except for the first parameter. So your print function would be:
```Swift
print(fullName("Phil", lastName: "Hanson"))
```
Also you can have external parameter names to use everywhere if you like to:
```Swift
func fullName( first firstName: String,  second lastName: String) -> String {
     return firstName + lastName
}
print(fullName(first: "Phil", second: "Hanson"))
```
Let me know if you have any questions!
