No, iOS is not open source. iOS is the operating system that runs on iPhones, iPads, and iPod Touches. It is developed and maintained by Apple and is proprietary software. Apple does not allow anyone to access the source code or modify the system. Apple has also restricted the ability to install software on iOS devices, limiting the user's control over the system. This means that users are limited to using the software as it is provided by Apple and cannot make any changes or customizations without Apple's permission. This also means that Apple must address any security flaws or bugs rather than be able to fix them with open-source software.
