With Swift, we get Playground that’s allows us to experiment learn. But for those of us still in Objective-C and don’t really care for the new language or can’t touch it until lucky enough to work on a new project, we now have Playground for Objective-C thanks to Krzysztof Zabłocki.
You can find the repository at https://github.com/krzysztofzablocki/KZPlayground.
He also made couple of screencasts. See below.
