背景：
iOS11后苹果提供 NEHotspotConfigurationManager 类直连周边Wi-Fi，iOS11前只能跳转到系统设置界面手动连接Wi-Fi 。

//存在已经连接的情况，error code = 13 优先考虑isSuccess

// 将连接wifi api返回的error 转化为 NEHotspotConfigurationError 类型
let errorCode = error != nil ? NEHotspotConfigurationError.init(
rawValue: ((error as NSError?)?.code)!

/// 获取iPhone当前连接的WiFi SSID
/// - Returns: SSID
public static func getWiFiSSID() -> String? {
if #available(iOS 13.0, *) {
//系统版本高于13.0 未开启地理位置权限 需要提示一下
if CLLocationManager.authorizationStatus() == CLAuthorizationStatus.notDetermined {
let locationManager = CLLocationManager()
locationManager.requestWhenInUseAuthorization()
}
}
if let interfaces = CNCopySupportedInterfaces(),
let interfacesArray = CFBridgingRetain(interfaces) as? [AnyObject],
interfacesArray.isEmpty == false {
let interfaceName: CFString = interfacesArray[0] as! CFString
let ussafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
let interfaceData = ussafeInterfaceData as? [String: Any]
let ssid = interfaceData?["SSID"] as? String

}
}
注意事项：
- 每次请求自动连接时，都会有系统弹框请求用户授权。
- 在自动连接网络后，可能存在网络无法立即请求通的情况， 可以用轮询方式监听。
