Answer 1

void SetWiFiMode(BOOL mode)
{
    void* manager = WiFiManagerClientCreate(kCFAllocatorDefault, nil);
    if (mode)
    {
        WiFiManagerClientSetProperty(manager, CFSTR("AllowEnable"), kCFBooleanTrue);
    }
    else
    {
        WiFiManagerClientSetProperty(manager, CFSTR("AllowEnable"), kCFBooleanFalse);
    }
    CFRelease(manager);
}

To use this your application entitlements should have com.apple.wifi.manager-access key with boolean value set to true. All functions can be found in private MobileWiFi.framework
