One of the things that Apple talked about in the end was Swift. They mainly talked about a new app for iPad called Swift Playground. Xcode on Macs already has a playground feature built in. However, this app is mainly geared towards people learnig how to code. The app will take you through different games and lessons that will help teach you the language. After each lesson it will test you and see what you’ve learned.
This app will be coming to the iPad this fall and is available to developers today.
