问题描述：
以下代码给出了编译器错误使用未声明的类型 AutoreleasingUnsafePointer"
The following code gives a compiler error "Use of undeclared type AutoreleasingUnsafePointer"

如 文档修订历史
更新指针部分以反映 UnsafePointer 已替换为 UnsafeMutablePointer，ConstUnsafePointer 已替换为 UnsafePointer>，并且 AutoreleasingUnsafePointer 已被替换为 AutoreleasingUnsafeMutablePointer.
Updated the Pointers section to reflect that
UnsafePointerhas been replaced withUnsafeMutablePointer,ConstUnsafePointerhas been replaced withUnsafePointer, andAutoreleasingUnsafePointerhas been replaced withAutoreleasingUnsafeMutablePointer.
所以你必须使用AutoreleasingUnsafeMutablePointer
