What's New in Codewise
1.4
October 20, 2026
Codewise 1.4 adds Python Design Patterns, a new module with 16 hands-on challenges. Build a Singleton with a shared instance, lazy creation, __new__, and a reusable decorator, and see how it can leak state between tests. Then practice dependency injection: pass dependencies in, swap implementations, use a fake for testing, and wire it all together with a tiny container. Codewise now has more than 280 challenges across Python, Swift, JavaScript, Java, Kotlin, C#, and SQL, all with live error hints and instant results, no account and no subscription. Thank you for learning with Codewise! If it has helped you, a rating on the App Store makes a big difference for a small indie app.
