如何列出(po)Swift数组的内容？

环境:Swift,Xcode 6

如何获取Swift数组的数据项列表(po)？

以下是用于构建简单数组的Swift代码:

kindArray += "Two"
kindArray.append("Two")

var myStringArray: String[]
myStringArray = ["One", "Two"]
myStringArray.append("Three")
myStringArray += "Four"

var firstItem = myStringArray[0]

这是调试输出:

(lldb) po firstItem
"One"

(lldb) po kindArray
Some
 {
  Some = 0x0ffb0000 {}
}
(lldb) po myStringArray
size=1
 {
  [0] = {
    core = {
      _baseAddress = Builtin.RawPointer = 0x00000008
      _countAndFlags = 34718
      _owner = Some {
        Some = (instance_type = Builtin.RawPointer = 0x80000003)
      }
    }
  }
}

我得到的只是'一些'和'大小'.
我想展示一下内容.

Answer 1

做就是了:

po print(myStringArray)

Answer 2

您应该能够利用这些Printable或DebugPrintable协议.只需打印出description或debugDescription属性:

po myStringArray.description
po myStringArray.debugDescription
