About a year ago I forked an open-source “internal testing” tweak, added a small private framework, and embedded it in our iOS app signed with an enterprise certificate. Everything ran perfectly until the latest app update. Now, the moment the tweak tries to replace the live camera feed with a pre-recorded video the whole app terminates. Here’s what I already know: • The tweak hooks into both the User Interface layer and the app’s data pipeline. • Its core job is Camera Input Handling—specifically swapping the AVCaptureDevice feed for a video file during tests. • The crash occurs exactly at the hand-off point when that swap happens. I’ll upload the full device crash log and the console trace in chat. I need you to: 1. Inspect the log, pinpoint the breaking change in the updated binary or private framework symbol set. 2. Patch the tweak (Objective-C / Swift, plus any required changes to the private framework) so it works with the current app version. 3. Send back a signed IPA or an Xcode project I can build that no longer crashes when video replaces the camera feed. Please be comfortable with reverse-engineering symbols, private APIs, and AVFoundation quirks. Once I confirm the patched build runs a complete test session without crashing, the job is done.
