CF provides:

• Primitive types for data (raw bytes, Unicode strings, numbers, calendar dates, UUIDs) and collections (arrays, sets, dictionaries)
• Application preferences management (CFPropertyList, Preferences Utilities)
• XML parsing
• Bundle handling
• File system I/O (CFReadStream, CFWriteStream, CFURL)
• Network and internet I/O (CFReadStream, CFWriteStream, CFURL, Socket Name Server Utilities, URL Access Utilities)
• Endianness translation (Byte Order Utilities)
• Interprocess communication (CFMachPort, CFNotificationCenter)
• Run loops
• Very basic graphical user interfaces (CFUserNotification)

Much of the Foundation Kit is implemented using Core Foundation, and many of the basic types are toll-free bridged. Unlike Foundation Kit, Core Foundation's API is in C, not Objective-C.
