nehelper sent invalid result code [1] for Wi-Fi information request

//获取wifi名称
    func getUsedSSID() -> String {
        var currentSSID = ""
        if let interfaces:CFArray = 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)

        print(currentSSID)
        return currentSSID
    }

解决方案1

增加访问权限

添加 Capability -> Accesss WiFi Infomation

解决方案2

增加一个获取地理位置权限

import CoreLocation//导入位置包
 
CLLocationManagerDelegate//在vc里增加一个地理位置管理器代理
 
var locationManager:CLLocationManager?//定义一个地理管理器
 
//在viewDidLoad里输入代码
self.locationManager = CLLocationManager()
self.locationManager?.delegate = self
self.locationManager?.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager?.distanceFilter = 1000.0
self.locationManager?.requestWhenInUseAuthorization()
self.locationManager?.requestAlwaysAuthorization()
self.locationManager?.startUpdatingLocation()

info.plist文件添加

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>AlwaysAndWhenInUseUsageDescription</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>AlwaysUsageDescription</string>
<key>NSLocationUsageDescription</key>
<string>UsageDescription</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>WhenInUseUsageDescription</string>
