ALTOOL: Validation failed (409) The app references non-public selectors setRequestErrorCode

[gabors]

When using mux-stats-sdk-avplayer 4.8.2 and stats-sdk-objc 5.6.0, build app for distribution and attempting to upload to AppStoreConnect I get the following validation error:

Updating to this latest MUX version is the only change in this upload. I have confirmed that a new build from the previous commit uploads just fine.

I've looked at your sources and saw these.

it is likely a false positive from Apple, but you may want to name your requestErrorCode something else.

I agree this is a false positive on their part, might be worth noting that the Swift code above is new though. I also don't get this validation error when submitting so it may have something to do with build settings.

Possibly unrelated, but it seems some others encountered a similar issue when submitting a debug build.

@CFKevinRef I tested with Mux SDK 4.9.0 on Xcode 26 and I’m still hitting the same validation error for the iOS app (though not for Mac Catalyst or tvOS).

At this point, we’ll need to stay on the older working 4.7.0 release. It would really help if you could take a closer look into these issues, because the “works on my box” response doesn’t address the fact that validation is failing on our side.
