Printing all values in CoreStoreObject?

[cdelaet]

Would it be possible to make CoreStoreObject to implement CustomStringConvertible by default? It would be nice if print(myCoreStoreObject) printed all keys and their values out of the box. I use that feature a lot to verify / debug my code.

That’s not what CustomStringConvertible is for. You want CustomReflectable or CustomDebugStringConvertible (I’m not sure why that last one exists).

On a related note, Core Data documentation explicitly discourages overriding description to fire a fault. I implement TextOutputStreamable instead. In fact, I never add conformance to CustomStringConvertible directly, only through LosslessStringConvertible. TextOutputStreamable is more efficient, and takes priority for almost everything. It also doesn’t leave uselessly identical properties everywhere.
