We use mix of Objc and Swift.
Here is the swift method, that is shown in crash report:
		@objc
func downloadVideosForShow(showInfo: ShowsAPI, completionBlock:@escaping(() -> Void)) {
var videos = [VideoAPIVideo]()
self.downloadVideosViaVIDEOAPI(searchParams: getParamsForEpisode(showInfo)) { results in
if !results.isEmpty {
videos.append(contentsOf: results)
}
self.downloadVideosViaVIDEOAPI(searchParams: self.getParamsForClips(showInfo)) { results in
if !results.isEmpty {
videos.append(contentsOf: results)
}
self.videoData = videos
completionBlock()
}
}
}
func getParamsForEpisode(_ showInfo: ShowsAPI) -> VideoAPISearchParams {
let searchParameters = VideoAPISearchParams()
searchParameters.show_id = NSNumber(value: showInfo.showId)
searchParameters.sort = "%5Eepisode"
searchParameters.type = .episode
if let seasons = showInfo.seasons {
if seasons.count > 1 {
searchParameters.season = NSNumber(value: showInfo.getChosenSeasonNumber())
}
}
return searchParameters
}
So far we never able to reproduce this crash on our side.
We tried on both debug and Release build configurations though Xcode.
And zombies instrument didn't catch anything related to this.
We are not sure, if this bug is worth spending more time.
We use the latest Xcode version from App Store.

I have the nanopb.xcframework in my project that is used by FirebaseAnalytics.
This issue is reported recently, and never before.
ITMS-90338: Non-public API usage - The app references non-public symbols in CitytvVideoStaging: pbdecode, pbencode, pbistreamfrombuffer, pbostreamfrombuffer. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed. For further information, visit the Technical Support Information at http://developer.apple.com/support/technical/
What is the possible solution for this nanopb issue?
