Hello, I have a question regarding Apple's policy on third-party SDK signatures. I have reviewed the official documentation here: https://developer.apple.com/support/third-party-SDK-requirements/ Our app is developed in the following environment: Minimum Target: iOS 15 Xcode: 26.2 Engine: Unreal Engine 4.27.2 We are integrating the Firebase SDK into our project. However, we are experiencing app crashes caused by an issue within the GoogleAdsOnDeviceConversion.xcframework included in the Firebase SDK (related to a memory optimization issue in UE4). According to an official response from the Firebase team, this crash can be resolved by wrapping the Firebase SDK in a dynamic XCFramework. We have confirmed that this solution does indeed fix the crash. The problem is that wrapping the Firebase SDK in a custom dynamic XCFramework removes all of the original Firebase SDK signatures. The documentation on third-party SDK signatures, which I referenced earlier, states that a signature is required for the Firebase SDK, and this requirement also applies when repackaging it. This leads me to the following questions: Question 1: When we wrap and repackage the Firebase SDK, is it mandatory for the resulting XCFramework to still include the original Google LLC signature? Question 2: To resolve the crash, we intend to use the Firebase SDK by wrapping it in our own dynamic XCFramework (e.g., FirebaseWrapper.xcframework). When we do this, the resulting XCFramework loses the Google LLC signature, and consequently, the final built IPA's signature list does not contain any Firebase-related signatures. Will this be a reason for rejection during App Store review? Question 3: If we wrap the Firebase SDK in a dynamic XCFramework and then sign it with our own developer certificate, would this be a reason for rejection during App Store review?
