In swift 2, you don't have to call takeRetainedValue.

Replace the code interfaces.takeRetainedValue() as [String : AnyObject] with Array(arrayLiteral: interfaces).

Also remember change the code interfacesArray[0] as String into String(interfacesArray[0]).

Full code ：

public class SSID {
class func getSSID() -> String{
    var currentSSID = ""
    let interfaces = CNCopySupportedInterfaces()
    if interfaces != nil {
        let interfacesArray = Array(arrayLiteral: interfaces)
        if interfacesArray.count > 0 {
            let interfaceName =  String(interfacesArray[0])
            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
                print(ssiddata)
            }
        }
    }
    return currentSSID
}

}
