My take on assertions, code sample accompanying blog post at http://merowing.info/2013/07/expanded-use-of-asserts/
typedef NS_ENUM(NSInteger, kErrorCode) {
kErrorCodeInternal = 431432,
};
//! generate error and log it.
extern NSError *pixle_NSErrorMake(NSString *message, NSUInteger code, NSDictionary *aUserInfo, SEL selector);
#define AssertTrueOrReturnBlock(condition, block) do{ NSAssert((condition), @"Invalid condition not satisfying: %s", #condition);\
if(!(condition)) { block(pixle_NSErrorMake([NSString stringWithFormat:@"Invalid condition not satisfying: %s", #condition], kErrorCodeInternal, nil, _cmd)); return;} }while(0)
