Steps to reproduce

  1. Build iOS app with Xcode "Archive" functionality or with the flutter build ipa command.
  2. Distribute via Xcode.
  3. Wait for the TestFlight build to process.
  4. Distribute to external tester group.

Expected results

The build is distributed successfully.

Actual results

The build is removed from TestFlight with the following message:

Hello,

We noticed one or more issues with a recent submission for TestFlight review for the following app:

Froddo B2B
App Apple ID 6751342858
Version 1.0.0
Build 18
Please correct the following issues and upload a new binary to App Store Connect.

ITMS-91065: Missing signature - Your app includes “Frameworks/Flutter.framework/Flutter”, which includes Flutter, an SDK that was identified in the documentation as a commonly used third-party SDK. If a new app includes a commonly used third-party SDK, or an app update adds a new commonly used third-party SDK, the SDK must include a signature file. Please contact the provider of the SDK that includes this file to get an updated SDK version with a signature. For details about verifying the code signature for a third-party SDK, visit: https://developer.apple.com/documentation/xcode/verifying-the-origin-of-your-xcframeworks.
