I already found out that bool is a C-Type while BOOL is an Objective-C Type. bool can be true or false and BOOL can be YES or NO
For beginners it can be hard to distinguish these types. Is there anything bad that can happend if I use bool instead of BOOL?
BOOLis asigned char, whileboolis aint(in fact, it’stypedef‘d as such in Darwin when compiling with pre-C99 standards). From there, the usual consideration when promoting/demoting between integer types can be followed.
