Possible values ​​for [[UIDevice currentDevice] systemName];

What are the possible values [[UIDevice currentDevice] systemName]; ? In Apple’s docs , this does not give any examples of what can happen, but all I can get from it is the iPhone OS , even on the simulator. Are there other possibilities, and if not, why does this property even exist?

This is the name of the operating system, as the documents say. Initially, iOS was called "iPhone OS" (before the iPad), but I think they did not change systemName for compatibility reasons.

In the future, they may implement [UIDevice systemName] on (Mac) OS X, and on this platform it is likely to return Mac OS X or OS X

Current use of this method is rather limited, but you never know what ((partially) compatible) Apple or someone else's operating systems might produce in the future ...

for the iPhone, the operating system returned by Apple was "iPhone OS." In some versions of iOS 9 and for applications published after Xcode 8 running iOS 10, Apple has replaced the iPhone OS value with iOS.
