QUESTION
For connector c++ 1.1, in this example, it's quite easy to get values by specifying the column name (or alias name).
But when I upgraded to version 8.0 xdevapi, I found this feature is no longer supported.

Answered 2022-Jan-08 at 16:39All .metal files in an Xcode project that builds an application are compiled and built into a single default library.
_device->newDefaultLibrary()
return a new library object that contains the functions from the default library. This method returns nil if the default library cannot be found.
Since you are not using Xcode, you should manually compile Metal Shading Language source code and build a Metal library.
Then, at runtime, call the newLibrary(filePath, &error)
method to retrieve and access your library as a MTL::Library
object.
