App.swift" %}
struct <YOUR_PROJECT_NAME>App: App {
// Add the code below
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
}
{% endtab %}
{% endtabs %}
### 5-2. AppDelegate
{% tabs %}
{% tab title="Switft(AppDelegate.swift)" %}
import FlareLane
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Add the code below
// To subscribe later, set the 3rd parameter to false and then run .subscribe() later.
FlareLane.initWithLaunchOptions(launchOptions, projectId: "<INPUT_YOUR_PROJECT_ID>", requestPermissionOnLaunch: true)
return true
}
}
{% endtab %}
{% tab title="Objective-C(AppDelegate.m)" %}
@import FlareLane
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Add the code below
// To subscribe later, set the 3rd parameter to false and then run the .subscribe() later.
[FlareLane initWithLaunchOptions:launchOptions projectId:@"INPUT_YOUR_PROJECT_ID", requestPermissionOnLaunch:true];
}
{% endtab %}
{% endtabs %}
### 5-3. Notification Service Extension
Run Xcode again and edit the extension's file. Delete the pre-filled codes and only inherit `FlareLaneNotificationServiceExtension`.
{% tabs %}
{% tab title="Swift(NorificationService.swift)" %}
import FlareLane
class NotificationService: FlareLaneNotificationServiceExtension {
}
{% endtab %}
{% tab title="Objective-C(NotificationService.h/.m)" %}
```objectivec
// NotificationService.h
@import FlareLane;
@interface NotificationService : FLNNotificationServiceExtension
@end
// NotificationService.m
#import "NotificationService.h"
@implementation NotificationService
@end
```
{% endtab %}
{% endtabs %}

## 6. Test
After completing all the steps, build and run your app. Devices that subscribe to push notifications will be automatically added to FlareLane console's **All Devices**.
Before actual deployment, be sure to verify that the push notifications are being received properly on the device and that the statistics are accurately recorded when the push notifications are clicked.
***
## 7. Identify your user
FlareLane's device is 'anonymous' and you can match the device with your user based on the unique user ID that identifies your user.
{% hint style="info" %}
Setting up [User ID](/data-integration/user-id.md) has many benefits. You can distinguish whether a user has signed-up, and push notifications can be sent based on the User ID.
{% endhint %}
Usually, when a user sign-up or log-in, you should execute `setUserId`.
{% tabs %}
{% tab title="Swift" %}
```swift
FlareLane.setUserId(userId: "USER_ID")
```
{% endtab %}
{% tab title="Objective-C" %}
```objectivec
[FlareLane setUserIdWithUserId: @"USER_ID"];
```
{% endtab %}
{% endtabs %}
