推荐答案

不可能获得所有可用的wifi网络名称和信息. 但只能获得当前连接的网络的SSID(SSID只是网络名称的技术术语).

It is not possible to get all the available wifi networks names and information. BUT it is only possible to get the SSID (SSID is simply the technical term for a network name) of the network that you are currently connected to.

此类仅显示您连接的wifi网络名称-

This class will show only the wifi network name you are connected to -

    import UIKit
    import SystemConfiguration.CaptiveNetwork

    class ViewController: UIViewController {

        @IBOutlet weak var label: UILabel!

        override func viewDidLoad(){
            super.viewDidLoad()
            let ssid = self.getAllWiFiNameList()
            print("SSID: \(ssid)")
        }
        func getAllWiFiNameList() -> String? {
            var ssid: String?
            if let interfaces = CNCopySupportedInterfaces() as NSArray? {
            for interface in interfaces {
            if let interfaceInfo = CNCopyCurrentNetworkInfo(interface as! CFString) as NSDictionary? {
                        ssid = interfaceInfo[kCNNetworkInfoKeySSID as String] as? String
                        break
                    }
                }
            }
            return ssid
        }
    }

输出-(我连接到的网络名称)

OUTPUT- (Network name where i am connected to )

要对此进行测试，您需要将物理设备(iPhone)连接到您的PC.

To test this you need a physical device (iPhone) connected to your pc.
