catalina xcode11.3 iOS 13.3运行日志报错 [] nehelper sent invalid result code [1] for Wi-Fi information request

• 这个版本的xcode以不允许获取WiFi名称

#import<SystemConfiguration/CaptiveNetwork.h>

- (NSString *)ssid
{
    NSString *sidStr = @"";
    CFArrayRef ssidArray = CNCopySupportedInterfaces();
    if (ssidArray != nil) {
        CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(ssidArray, 0));
        if (myDict!=nil) {
            NSDictionary *dict = (NSDictionary*)CFBridgingRelease(myDict);
            sidStr = [dict valueForKey:@"SSID"];
        }
    }
    return sidStr;
}

可以用此方法前去验证
