I want to learn the Apple Swift programming language. I looked online and was a bit overwhelmed. Can anybody suggest some good places to start learning Swift for free?
I'd suggest Makeschool.com
They're similar to Codeacademy but they're solely focused on iOS development.
App Development with Swift in the iBooks store free. That book will get you programming. it has a link in it to download project files you can use in playground inside of Xcode. Also get The Swift Programming Language book which is the Documentation for the language all free.
