When people think about jailbreak, they often associate it with bypassing Apple’s restrictions. From a technical perspective, jailbreak provides a powerful lens to observe and understand iOS architecture, security, and runtime behavior.
This series does not encourage unauthorized jailbreak usage. Instead, jailbreak is treated as a technical learning tool to understand how iOS is designed and operates as a full operating system.

Why should developers care about jailbreak?
Even if you never jailbreak a real device, the insights gained from jailbreak research provide significant value for developers.
- Understand trust boundaries within iOS
