# Notification profile mismatch

#### iOS build failure: Notification provisioning profile mismatch

If your app build is failing, your build is not working, or your download is not completing and you see the error:

*“It seems your app build has encountered an issue. The Bundle ID of the uploaded Notification Provisioning Profile does not match this app.”*

This means the provisioning profile uploaded for push notifications does not match the required Notification Bundle ID.

This mismatch causes the iOS build failure.

#### Why this build failure happens

1. The main app provisioning profile was reused for notifications
   * The same provisioning profile was uploaded for both the app and notifications
   * A separate notification provisioning profile was not created
2. The Notification Bundle ID was not created correctly
   * The *AppNotificationServiceExtension* identifier does not exist
   * The wrong identifier was selected during profile creation

#### How to fix this iOS build failure

1. Create a new notification bundle identifier
   * Log in to your [Apple Developer account](https://developer.apple.com/)
   * Go to Certificates, Identifiers & Profiles
   * Navigate to Identifiers
   * Click the + icon
   * Select App IDs and click Continue
   * Choose App and click Continue
   * Enter the Notification Bundle ID in this format:

     app.yourapp.bundleid.ios.AppNotificationServiceExtension
   * Do not enable any additional capabilities
   * Click Continue and then Register

{% hint style="warning" %}
The Notification Bundle ID must end with AppNotificationServiceExtension and should be created separately from your main app bundle ID.
{% endhint %}

2. Generate a notification provisioning profile
   * Go to Profiles
   * Click the + icon
   * Under Distribution, select App Store Connect
   * Select the newly created AppNotificationServiceExtension identifier
   * Select the same distribution certificate used for the main app
   * Enter a name for the provisioning profile
   * Click Generate
   * Download the provisioning profile

{% hint style="warning" %}
Select the same distribution certificate used for the main app build. Only the Bundle ID should be different.
{% endhint %}

3. Upload the notification provisioning profile
   * Go to your app dashboard
   * Navigate to Notifications
   * Click on Build Settings
   * Upload the downloaded Notification Provisioning Profile in the relevant section
4. Rebuild your app
   * Go to the [Download](https://app.appmysite.com/app/download) dashoboard
   * Click Rebuild under the iOS app card

Once the correct notification provisioning profile is uploaded, your build failure should be resolved and the download should complete successfully.
