When Apple introduced Swift, they also introduced playgrounds, a way of prototyping and playing with Swift in Xcode without compiling to a simulator or device. Now there's the Swift Playgrounds app for the iPad, which extends their power to a mobile, interactive environment. Playgrounds are a versatile system for app development, whether you're prototyping ideas, documenting new frameworks, or learning to code. The possibilities are limited only by your imagination. In this course, Steven Lipton explores playgrounds for Xcode and for the iPad. Find out how to use these new ecosystems to quickly write code (even without a keyboard!), debug and test at lightning speed, create interactive presentations, and build courses to teach programming concepts in a fun and interactive way. Learn what you can do with these powerful tools for prototyping, documentation, and education.
