Cocoa: Get Darwin version at runtime

How can I get the darwin version at runtime? I know that I can get the macOS or iOS version using [[NSProcessInfo processInfo] operatingSystemVersion], but I want the Darwin version.

There are tables on the internet linking macOS and iOS releases to a darwin version, but i want to implement this future-proof.

Solution

  • Use the uname() POSIX/BSD library function. You declare a variable of type struct utsname and pass in its address. The release field of the struct will contain a C string with the Darwin version number, such as "16.3.0". If you want the individual components as integers, you'll have to parse it yourself.
