'''QuickDraw''' was the 2D [[computer graphics|graphics]] library and associated [[application programming interface]] (API) which is a core part of [[classic Mac OS]]. It was initially written by [[Bill Atkinson]] and [[Andy Hertzfeld]].<ref>{{cite web|url=https://www.folklore.org/StoryView.py?project=Macintosh&story=Negative_2000_Lines_Of_Code.txt|title=Folklore: -2000 Lines of Code|website=folklore.org}}</ref> QuickDraw still existed as part of the libraries of [[Mac OS X]], but had been largely superseded by the more modern [[Quartz (graphics layer)|Quartz]] graphics system. In [[Mac OS X Tiger]], QuickDraw has been officially [[deprecation|deprecated]]. In [[Mac OS X Leopard]] applications using QuickDraw cannot make use of the added 64-bit support. In [[OS X Mountain Lion]], QuickDraw header support was removed from the operating system. Applications using QuickDraw still ran under OS X Mountain Lion to macOS High Sierra; however, the current versions of Xcode and the macOS SDK do not contain the header files to compile such programs.
