Learn what's new in Swift 4.1 with a playground – Hacking with Swift

See the code, run the code, edit the code

Previously I wrote about the new features in Swift 4.1, but it's a lot more fun to see things in action and experiment yourself.

So, I just released an Xcode playground that demonstrates the new features introduced in Swift 4.1, complete with examples that I hope make them easy to understand and apply in your own work:

• Synthesized Equatable and Hashable
• Key decoding strategy in Codable
• Conditional conformances
• Recursive constraints on associated types
• Build configuration import testing
• Target environment testing
• flatMap() is now (partly) compactMap()

Info

The playground is available on GitHub, so I hope you'll try it for yourself:

I should add that the task of building this playground was made much easier thanks to previous work done by Ole Begemann.
