iOS is an operating system developed by Apple for mobile devices such as the iPhone, iPad, and iPod touch. It was first released in 2007 and has since become the most popular mobile operating system in the world.
Why Check the Version of iOS Installed on Your Device?
As an iOS developer, it is important to know which version of iOS your device is running on because it can affect the compatibility of your app with that device.

Additionally, knowing the version of iOS installed on your device can help you determine if any updates are required for your app. If there are security vulnerabilities or other issues with the current version of iOS, it is important to update your device as soon as possible to ensure that your app and personal data are protected.
