Conclusion

In conclusion, JSON (JavaScript Object Notation) serves as a lightweight and human-readable data interchange format. Its simplicity in parsing and readability make it a preferred choice for data transfer and persistence. In iOS development, JSON helps simplify persisting data in a single JSON file.

You incorporated JSON for persistent data storage in the JoyJotter app. The app achieves seamless saving and retrieval of jokes in the Document directory. The decision-making process regarding when to write changes to the JSON file — either with each ViewModel update or upon the app moving to the background — involves a thoughtful evaluation of factors such as real-time updates, data size, and battery usage. By strategically employing these techniques, the app successfully maintains its humor-filled content across different app launches, providing a delightful and continuous user experience.
