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)

Workaround to vanilla UICollectionView+UICollectionViewFlowLayout using non-integral origins, leading to blurry cells.
@implementation BHSCollectionViewFlowLayout
- (NSArray *)layoutAttributesForElementsInRect:(CGRect)rect {
NSArray *allAttrs = [super layoutAttributesForElementsInRect:rect];
for (UICollectionViewLayoutAttributes *attributes in allAttrs) {
attributes.frame = CGRectIntegral(attributes.frame);
}
return allAttrs;
}

Set symbol breakpoint on objc_msgSend then setup this debug command to log all methods called in iOS Simulator. If you want to do device debugging change esp+4 register to r0, esp+8 to r1 Found long ago somewhere on stackoverflow.
expr -- (void)printf("[%s, %s]\n",(char *) object_getClassName(*(long*)($esp+4)), (char *) *(long *)($esp+8) )
