在Swift 3中檢索WiFi網絡

我試圖找出該機器連接到的SSID。我發現的所有東西都是針對iOS的，並沒有用處。使用下面的代碼，我得到一個錯誤，指出：''CNCopyCurrentNetworkInfo'不可用「，因爲它是iOS特定的。什麼是macOS等價物？在Swift 3中檢索WiFi網絡

import SystemConfiguration.CaptiveNetwork 

    var wifiNetwork = "Unknown" 
    if let interfaces = CNCopySupportedInterfaces() { 
     for i in 0..<CFArrayGetCount(interfaces){ 
      let interfaceName: UnsafeRawPointer = CFArrayGetValueAtIndex(interfaces, i) 
      let rec = unsafeBitCast(interfaceName, to: AnyObject.self) 
      let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)" as CFString) 

      if let unsafeInterfaceData = unsafeInterfaceData as? Dictionary<AnyHashable, Any> { 
       wifiNetwork = (unsafeInterfaceData["SSID"] as? String)! 
      } 
     } 
    }

我用下面的代碼來獲取當前的SSID ，在檢查互聯網連接。

import CoreWLAN 

let wifiNetwork = CWWiFiClient.shared().interface()!.ssid()!

複製在這裏：

func currentSSIDs() -> [String] { 
    guard let interfaceNames = CNCopySupportedInterfaces() as? [String] else { 
     return [] 
    } 
    return interfaceNames.flatMap { name in 
     guard let info = CNCopyCurrentNetworkInfo(name as CFString) as? [String:AnyObject] else { 
      return nil 
     } 
     guard let ssid = info[kCNNetworkInfoKeySSID as String] as? String else { 
      return nil 
     } 
     return ssid 
    } 
}

CNCopyCurrentNetworkInfo僅可在IOS和tvOS根據[文檔】（https://developer.apple.com/documentation/systemconfiguration/1614126-cncopycurrentnetworkinfo）。我無法在任何地方找到macOS的模擬器。 – user2625833
