        We do not understand why , in the following code sequence , all the get functions return the right value , and not the first one SCNetworkInterfaceGetConfiguration which returns nothing ?

        <

                let arr: CFArray = SCNetworkInterfaceCopyAll()

                let interfaces: [SCNetworkInterface] = arr as! [SCNetworkInterface]

                for interface in interfaces {

                 

                    let intDic: CFDictionary? = SCNetworkInterfaceGetConfiguration(interface)

                    if intDic != nil {

                         print (intDic)

                     }

         

                    if let bsd: String = SCNetworkInterfaceGetBSDName(interface) as String? {

                        print (bsd)

                    }

                 

                    if let adress: String = SCNetworkInterfaceGetHardwareAddressString(interface) as String? {

                        print (adress)

                    }

                 

                    if let type: String = SCNetworkInterfaceGetInterfaceType(interface) as String? {

                        print (type)

                    }

                 

                    if let local: String = SCNetworkInterfaceGetLocalizedDisplayName(interface) as String? {

                        print (local)

                    }

                    let typeId: CFTypeID = SCNetworkInterfaceGetTypeID()

                 

                    if let intSup: CFArray = SCNetworkInterfaceGetSupportedInterfaceTypes(interface) as CFArray? {

                        print (intSup)

                    }

                    if let prot: [String] = SCNetworkInterfaceGetSupportedProtocolTypes(interface) as? [String] {

                        print (prot)

                    }

                }
