Question

Xcode Beta3 中的 CMutablePointer 和 CConstPointer 发生了什么？

在 Beta2 中成功编译的代码因错误而失败:

Use of undeclared type 'CMutablePointer'

Answer 1

分别使用UnsafePointer和ConstUnsafePointer。

来自发行说明:

APIs imported from C that use C pointers are now imported with a much simpler API type structure which is more predictable, preserves const mutability in more cases, and preserves __autoreleased pointer information.  Now you will see UnsafePointer, ConstUnsafePointer, AutoreleasingUnsafePointer, etc.  Function pointers are also imported now, and can be referenced and passed around.  However, you cannot call a C function pointer or convert a closure to C function pointer type.!
