The excellent playground feature in Xcode 6 provides a great way to create interactive programming examples, but unfortunately only works with Swift.
Here’s a library submitted by Krzysztof Zablocki providing an extensive feature set for creating Playgrounds in Objective-C called KZPlayground.
Some of the features of KZPlayground as stated in the readme include:
- Faster than Swift playgrounds (a lot)
- Extra controls for tweaking:
- Auto-animated values
- Synchronizing DSL’s
- IDE agnostic, once you run it, you can modify the code even from vim.
- Full iOS simulator and access to all iOS features, so you can prototype production ready code.
- Nice DSL for rapid prototyping
- CocoaPods support, so you can add it to existing projects to experiment
- Open source, anyone can contribute to make them better!
An example project is included.
