These are the resulting playgrounds of my talk at SwiftConf 2016 and do iOS 2016
To play around with it, airdrop the SwiftConf.playgroundbook or do iOS.playgroundbook to you iPad running iOS 10 with Swift Playgrounds installed and it will automatically open.
Because Playground Books aren't compatible with the latest XCode, the files SwiftConf XCode.playground and do iOS XCode.playground contain an XCode compatible version of the playground to play around with the code on the Mac. Unfortunately UIImagePickerController isn't working in XCode, so you have to use the iOS version to get that to work.
