The issue here might be understanding the term "deprecated". Apple uses this to indicate that a feature has been earmarked for future removal. It does not mean the feature is already removed. Unfortuanately, it is very commonly misinterpretted to mean a feature has been removed. I have even seen some developers, including Microsoft employees, use the term as "the feature is gone". I have also seen Microsoft use it correctly, as Apple usually does, as a warning that the feature is going EOL but has not been removed yet. Deprecation really means "we're serving you notice that this feature will be gone in a future release but not yet". Any other use is incorrect.
