Theoretically just: let u = MGCopyAnswer("HardwarePlatform") However, the problem is that MGCopyAnswer is a private method, and thus you have to define an interface for it. You can't do that in Swift, however you can do it by creating a bridging header for Swift. So you'd need to add a bridging-header.h to the project, then set the compile target up to use the bridging header, and finally add this to the bridging header: #include <CoreFoundation/CoreFoundation.h> #if __cplusplus extern "C" { #endif CFPropertyListRef MGCopyAnswer(CFStringRef property); #if __cplusplus } #endif
