I had an entity object, some properties are nil some arn't. I want to list all non-nil properties and corresponding values.
For example my entity looks like:
allValuesWithAuthFields: returns a dictionary with property name as key, property value as value.
The engine part:
Oh, be sure you import objc/message.h, #import <objc/message.h>.
As you can see I use a marco @keypath(self, type) instead of a pure string.
Which is EXTKeyPathCoding provided by libextobjc, automatically checks key paths at compile-time.
