We get a crash in CFNetwork for some iPhone7 and iPhone XR devices in BetaTestFlight. We have submitted the app to Beta but for some devices it gets a crash. In code the crash happens when creating a URL ( let url: URL = URL(string: urlString)! ) I know the forced unwrapping is the one that creates the crash but it only happens in some devices. In most of the devices it run completely right. Here i post the crash threads.
