iOS & macOS development

Impeller is a Distributed Value Store (DVS) written in Swift. It was inspired by successful Distributed Version Control Systems (DVCSes) like Git and Mercurial, and appropriates the concept and terminology for use with application data, rather than source code files.

With Impeller, you compose a data model from Swift value types (structs), and persist them locally in a store like SQlite. Values can be pushed to services like CloudKit, and pulled down to other devices, to facilitate sync across devices, and with web apps.

Just wrote this class, MKiCloudSync (100 lines of code) that auto syncs your NSUserDefaults to iCloud.

How to use?
All you need to do is to enable iCloud key value store entitlements, copy the files and forget about the rest.
