Int and String in the same function

I've been messing around with functions in Xcode and tried to add a string and an Int at the same time. But i can't seem to figure out how. What's the proper way to add a string and an int into the same function?

you are missing the return type of String after the ->. the parenthesis around the string is also unnecessary

func yourAge (yourAge: Int) -> String {
     return "oh so you're \(yourAge)?"
}
