These are the resulting playgrounds of my talk at SwiftConf 2016
To play around with it, airdrop the SwiftConf.playgroundbook to you iPad running iOS 10 beta 8 and it will automatically open in Swift Playgrounds. Unfortunately Swift Playgrounds is removed from the iOS 10 GM.
Because Playground Books aren't compatible with the latest XCode Beta 6, the file SwiftConf XCode.playground contains 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.
