XCode 8, cannot receive push notification - push-notification

Question

After upgrade to XCode 8, my iphone with IOS 10 cannot receive push notification any more.
I have enable the "Automatically manage signing".
I re-generate the certificate from Apple website, the universal one.
My local codes is running without any error.
I can get device token correctly with the codes (swift 3):
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
print("start didFinishLaunchingWithOptions")
// Register the supported interaction types.
let types = UIUserNotificationType([.alert, .badge, .sound])
let mySettings = UIUserNotificationSettings(types: types, categories: nil)
UIApplication.shared.registerUserNotificationSettings(mySettings)
// Register for remote notifications.
UIApplication.shared.registerForRemoteNotifications()
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("start didRegisterForRemoteNotificationsWithDeviceToken")
let deviceTokenString = ((deviceToken as NSData).description.trimmingCharacters(in: CharacterSet(charactersIn: "<>")) as NSString).replacingOccurrences(of: " ", with: "")
....
}
My PHP in server side always return 200 which is successful.
$ch = curl_init();
if (!defined('CURL_HTTP_VERSION_2_0')) {
define('CURL_HTTP_VERSION_2_0', 3);
}
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
$pem_file = '/var/my.pem';
$pem_secret = 'xxxxxx';
$apns_topic = 'xxxxxx';
$apns_expiration = 2;
$change_alert = "{
\"aps\": {
\"alert\": \"$alert_message\",
\"badge\": $badge,
\"sound\": \"default\"
},
\"xxxxxxxx\": \"$xxxxxx\"
}";
$url = "https://api.development.push.apple.com/3/device/$device_token";
//$url = "https://api.push.apple.com/3/device/$device_token";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $change_alert);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("apns-topic: $apns_topic", "apns-expiration: $apns_expiration"));
curl_setopt($ch, CURLOPT_SSLCERT, $pem_file);
//curl_setopt($ch, CURLOPT_SSLCERTPASSWD, $pem_secret);
$response = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
My apns-topic is the same with my app bundle id.
Any idea for this issue?
BTW, XCode 8 is not as stable as the previous version.
