IOS получает push-уведомление от Google GCM, когда приложение не работает в swift

Я использую iOS 9.2 и Swift 2
и я использую Google GCM для отправки уведомлений с php-сервера пользователям iOS
все в порядке, когда приложение на переднем плане или в фоновом режиме, но когда приложение больше не работает, уведомление не появляется

это мой код на стороне сервера

$access_key =  'access_key';
$registrationIdsIOS = ["registrationIdsIOS"] ;

// prep the bundle
$msg = array
(
'message'   => 'message',
'title'     => 'title',
'subtitle'  => 'This is a subtitle. subtitle',
'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
'vibrate'   => 1,
'sound'     => 1,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
$fields = array
(
'registration_ids'  => $registrationIdsIOS,
'data'          => $msg,
'content_available' => true

);

$headers = array
(
'Authorization: key=' . $access_key,
'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send');
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;

и это моя сторона IOS
