Don't worry about the as!. It is a forced cast from an optional to a specific type. In Objective-C you just have a pointer; type conversions are handled more loosely.

Thus,

NSString *name = SCNetworkInterfaceGetBSDName(interface);

should suffice.

What could be the interface. when i give en0, it is giving error

You should take the result of SCNetworkInterfaceCopyAll(), not provide your own. You can examine the result of that call to find out what the interface you need should be.
