Booleanis an old Carbon keyword (historic Mac type), defined as anunsigned char.BOOLis an Objective-C type defined assigned char.boolis a defined version of the_Boolstandard C type. It’s defined as anint. UseBOOL.Edit (2019): Apple talks about the underlying implementation of
BOOLin some new documentation. Basically, on macOS,BOOLis still ultimately asigned char, but on iOS and related platforms, it a native Cboolunderneath.
