My requirement : I need an Objective C API which can give me version of "QuickTime Player" installed in system.
Earlier, I was using Gestalt API to fetch QuickTimeVersion in following way :
OSErr result = Gestalt(gestaltQuickTimeVersion, version);
However it has stopped working in MacOs 10.15 Catalina. This piece of code now gives gestaltUndefSelectorErrresult code. We're aware of the fact that this API has been deprecated now. However, I am unable to find any repacement of this API. My requirement, as stated above, is to get version of QuickTime Player via Objective C API because my code base is in C++.
