在OS X中显示与Swift的所有可用WIFI连接

但最好不使用带编码的名称,因此我们还将使用CWWiFiClient.sharedWiFiClient().interface()返回默认的WIFI接口.

管理所有这些的类的示例：

class Discovery {

    var currenTinterface: CWInterface
    var interfacesNames: [String] = []
    var networks: Set<CWNetwork> = []

    // Failable init using default interface
    init?() {
        if let defaulTinterface = CWWiFiClient.sharedWiFiClient().interface(),name = defaulTinterface.interfacename {
            self.currenTinterface = defaulTinterface
            self.interfacesNames.append(Name)
            self.findNetworks()
        } else {
            return nil
        }
    }

    // Init with the literal interface name,like "en1"
    init(interfaceWithName name: String) {
        self.currenTinterface = CWInterface(interfacename: Name)
        self.interfacesNames.append(Name)
        self.findNetworks()
    }

    // Fetch detectable WIFI networks
   func findNetworks() {
        do {
            self.networks = try currenTinterface.scanForNetworksWithSSID(nil)
        } catch let error as NSError {
            print("Error: \(error.localizedDescription)")
        }
    }

}

使用默认界面调用它：

if let discovery = Discovery() {
    print(discovery.networks)
    for network in discovery.networks {
        print(network.ssid!)
    }
}

或者使用接口名称：

let discovery = Discovery(interfaceWithName: "en1")
let results = discovery.networks

结果包含所有扫描的网络：
