# Carousel, Slider and Thumbnail Push
### Step 1: Create a New **Notification Content Extension**
To create a new Notification Content Extension to your application:
1. On Xcode click **File > New > Target** and choose **Notification Content Extension.**
2. New class named `NotificationViewController` will be created. It should be extended from `NetmeraNotificationContentExtension` class. Your `NotificationContent` class should look like the following:
```swift
import UserNotifications
import UserNotificationsUI
import NetmeraNotificationContentExtension
class NotificationViewController: NotificationContentExtension {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceive(_ notification: UNNotification) {
super.didReceive(notification)
}
}
```
3. Enable **Capabilities** > **App Groups** for both your **application** and `NotificationContent` extension.
4. Add `bundle_identifier.group_name` to your app groups.
### Optional: Installing Notification Content Extension Using CocoaPods
If you're using a **Podfile** for dependency management, follow these steps along with the rest of the steps from 1 to 5:
* Install `NetmeraNotificationContentExtension` in your Podfile,
* Install it to your extension target.
```ruby
pod "NetmeraNotificationContentExtension"
```
**Note:** If you're not using CocoaPods, you can skip this step.
### Step 2: Add Your `AppGroupName`
1. Add your `AppGroupName` in your Netmera-Config.plist.
```html
sdk_paramsapp_group_name // add this line in Config.plist
{YourAppGroupName} // add this line in Config.plist
use_ui_sceneapi_key{API_KEY}custom_events{YourCustomEvent}
```
If you don't have a Netmera-Config.plist see the step here [#id-1.-configure-with-netmera-plist](https://user.netmera.com/netmera-developer-guide/platforms/ios/sdk-integration#id-1.-configure-with-netmera-plist "mention").
### Step 3: Select Targets in Target Membership
1. Select **all three targets** in the Target Membership section on the right.
### Step 4: Select Main Project & Content Extension
1. Go to **Notification View Controller > Target Membership**.
2. Select both the main project and the content extension.
### Step 5: Info.plist Settings
#### Sample Content Extention Info.plist
```xml
NSAppTransportSecurityNSAllowsArbitraryLoadsNSExtensionNSExtensionAttributesUNNotificationExtensionUserInteractionEnabledUNNotificationExtensionCategoryNetmeraCarouselNetmeraGeneralUNNotificationExtensionInitialContentSizeRatio1NSExtensionMainStoryboardMainInterfaceNSExtensionPointIdentifiercom.apple.usernotifications.content-extension
```
#### 1. Receiving Http Media Contents
If you want to allow your application to receive http media contents follow these steps:
1. Click `Info.plist` under **Notification Content Extension,**
2. Add **App Transport Security Settings,**
3. Add **Allow Arbitrary Loads** under App Transport Security Settings and set it to **YES.**
#### 2. Enabling Slides in Carousel Notifications
To allow users to slide between multiple media items (such as images) in a notification:
1. Set `UNNotificationExtensionUserInteractionEnabled` to **YES**.
2. Add `UNNotificationExtensionCategory` as an array in **Info.plist** and include:
* `NetmeraGeneral`
* `NetmeraCarousel` (enables sliding between multiple media items)
{% hint style="info" %}
The `UNNotificationExtensionCategory` field does not appear automatically in **Info.plist**. You must **manually** enter and configure it.
{% endhint %}
### **Troubleshooting**
If push notifications do not display correctly:
1. Go to **Build Settings > Runpath Search Paths** in the extension target. Ensure the following paths are added:
```plaintext
@executable_path/../../Frameworks
@executable_path/Frameworks
@loader_path/Frameworks
```
2. Remove the **default label** in **MainInterface**.
