1.获取WiFi名称的代码：

private func getWiFiName() -> String? {
        guard let unwrappedCFArrayInterfaces = CNCopySupportedInterfaces() else {
//            print("this must be a simulator, no interfaces found")
            return nil
        }
        guard let swiftInterfaces = (unwrappedCFArrayInterfaces as NSArray) as? [String] else {
//            print("System error: did not come back as array of Strings")
            return nil
        }
        var wifiName: String?
        for interface in swiftInterfaces {
            print("Looking up SSID info for \(interface)") // en0
            guard let unwrappedCFDictionaryForInterface = CNCopyCurrentNetworkInfo(interface as CFString) else {
//                print("System error: \(interface) has no information")
                return nil
            }
            guard let SSIDDict = (unwrappedCFDictionaryForInterface as NSDictionary) as? [String: AnyObject] else {
//                print("System error: interface information is not a string-keyed dictionary")
                return nil
            }
            wifiName = (SSIDDict["SSID"] as? String)
        }
        return wifiName
    }

2.在iOS12和iOS13以后的版本上述代码返回为nil：

原因是iOS12以后的版本，需要额外设置权限信息，官网链接。

iOS13以后的版本，需要添加位置定位信息，用户同意使用后，才能获取wifi名称。

3.设置权限步骤：

3.1创建一个设置文件：

文件代码内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>aps-environment</key>
    <string>development</string>
    <key>com.apple.developer.associated-domains</key>
    <array>
        <string>applinks:demoapi.anniekids.net</string>
    </array>
    <key>com.apple.developer.networking.wifi-info</key>
    <true/>
</dict>
</plist>

3.2在Xcode中设置加载上面创建文件：

过程：Xcode->targent->Build Settings->Code Signing Entitlements->$(SRCROOT)/上述文件路径。
例如我的路径：$(SRCROOT)/项目名称/Classes/AppDelegate/文件名称.plist。

4.设置定位权限

4.1info.plist设置用户权限弹窗提示字符串

4.2代码

/// 定位权限
    static func checkLocation(isAlways: Bool, compelete: PermissionToolAuthorizeStatusCompelete?) {
        let status = self.getLocationStatus()
        if self.instence.locationManager == nil {
            self.instence.locationManager = CLLocationManager.init()
            self.instence.locationManager?.delegate = self.instence
        }
        switch status {
        case .none: do {
            self.instence.authorizeCompelete = compelete
            if isAlways {
                self.instence.locationManager?.requestAlwaysAuthorization()
            }
            else {
                self.instence.locationManager?.requestWhenInUseAuthorization()
            }
        }
        case .whenInUse: do {
            if isAlways {
                self.instence.authorizeCompelete = compelete
                self.instence.locationManager?.requestAlwaysAuthorization()
            }
            else {
                compelete?(.authorized)
            }
        }
        case .always:
            compelete?(.authorized)
        case .denied:
            compelete?(.denied)
        }
    }
