如何在Xcode Debugger中调用嵌套的Swift函数？

Question

In Xcode Debugger, how can I call a function inside of a function?

Code ( errorMessage is an instance method, and firstName & lastName are properties of self .)

func errorMessage() -> String? {
    func isValidName(name: String) -> Bool {
        return 1...50 ~= name.characters.count
    }

    var nameType: String?
    if !isValidName(firstName) {
        nameType = "First"
    } else if !isValidName(lastName) {
        nameType = "Last"
    }

    if let messagePrefix = nameType {
        return "\(messagePrefix) name must be between 1 & 50 characters."
    } else {
        return nil
    }
}

Debugger (while stopped at the first if statement above)

(lldb) p isValidName("Matt")
error: <EXPR>:1:1: error: use of unresolved identifier 'isValidName'
isValidName("Matt")
^~~~~~~~~~~
