About CloudKit and Quality of Service

However I'm not sure if there is anything within the Swift foundation that would make use of it.

Note discretionary means that the operation doesn't end on network errors but keeps re-trying on its own, I think its for 24 hours on iOS? I suppose this was done to simplify developer code but coming from traditional networking APIs it is a bit confusing.
