- init methods should return `instancetype` - get rid of [this ugly `_init` method](https://github.com/luckymarmot/LMGCDAsyncSocketMiddleware/blob/master/Source/LMGCDAsyncSocketReadOperation.h#L40) – replace by method inheritance - add nullability info to header files - add doc strings to methods in header files (especially for delegate methods) - declare `NS_DESIGNATED_INITIALIZER` - replace `+CRLFData` and `+CRLFCRLFData` by static `FOUNDATION_EXPORT NSData*` created on `+load`
