ios - how to cast an indirect pointer in Objective-C -

i trying work on keychain , following tutorial here unfortunately getting following error talks searching keychain

cast of indirect pointer objective-c pointer 'cftyperef *' (aka 'const void **') disallowed arc 

this code looks like

 osstatus status = secitemcopymatching((__bridge cfdictionaryref)searchdictionary,(cftyperef *)&result); 

any providing correct code on how cast indirect pointer appreciated.

use void * instead:

 osstatus status = secitemcopymatching((__bridge cfdictionaryref)searchdictionary,(void *)&result);
