A sample iOS app built using the Clean Swift architecture. Clean Swift is Uncle Bob's Clean Architecture applied to iOS and Mac projects. CleanStore demonstrates Clean Swift by implementing the create order use case described by in Uncle Bob's talks.
Ray Wenderlich (among others) wrote a pretty good swift style guide: https://github.com/raywenderlich/swift-style-guide
The main changes in Clean-Store are the OTBS bracing style and the split of protocol conformance into extensions (as seen in Approach 3 of the Refactoring table view data source and delegate methods blog entry at http://clean-swift.com/refactoring-table-view-data-source-and-delegate-methods/)
