Xcode - 類和覆蓋

Question

我是新的新swift編程。我嘗試建立一些簡短的代碼，我想不出是什麼原因導致的問題 代碼：

class fullname { 
    let firstname : String 
    let lastname : String 
    init(firstname : String, lastname : String) { 
     self.firstname = firstname 
     self.lastname = lastname 
    } 
    func conect() { 
     "\(firstname) \(lastname)" 
    } 
} 

class MyFirstFullName: fullname { 
    override func conect() { 
     print ("Mr \(firstname) \(lastname)") 
    } 

} 
let hello = fullname (firstname: "meitav", lastname: "Asulin") 

Xcode中寫我：__lldb_expr_132.fullname

難道我有我的代碼什麼問題？這個警告是什麼意思？

Answer 1

__lldb_expr_132.fullname不是錯誤或警告。它是變量hello的類型。

__lldb_expr_#引用隱式創建的模塊fullname給模塊中的類。

let hello = MyFirstFullname(firstname: "meitav", lastname: "Asulin") 
hello.conect()
