我试图使用此代码获取SSID

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func getSSID() -> String{
        var currentSSID = ""
        let interfaces = CNCopySupportedInterfaces()
        if interfaces != nil {
            let interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]
            if interfacesArray.count > 0 {
                let interfaceName = interfacesArray[0] as String
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData.takeRetainedValue() as Dictionary!
                    currentSSID = interfaceData[kCNNetworkInfoKeySSID] as! String
                    let ssiddata = NSString(data:interfaceData[kCNNetworkInfoKeySSIDData]! as! NSData, encoding:NSUTF8StringEncoding) as! String
                    // ssid data from hex …
