I'm having a hard time to debug a crash in our app. Our app is crashing in devices with iOS 9 and 10 when the user performs multitask and kill the app. So the issue is not that critical but it messes with our crash free statistics.
To get the things a little harder, we are only able to reproduce this issue when the app is downloaded from App Store.
Repro steps:
1) Download the app from App Store
2) Run the app
3) Perform multitask and kill the app
Repro rate in iOS 9 and 10 are 100%!
It's not practical to test our builds releasing the app in AppStore, so we need to find a way to reproduce this locally.
Things we tried:
1) Build using xcode (debug developer schema)
2) Build using xcode (release production schema)
3) Upload a build to testflight and check for crash logs in the device
4) Tried to download the app from app store and then replace with one of the xcode/testflight
5) Tried to uninstall the app store build first and then installed the one of the xcode/testflight
3) Repeated these steps like a trillion of times in multiple devices
The crash logs are attached at the end of my post. But what I can't understand is how a testflgith build is different from an app store build.
Maybe the iOS handle the app differently when downloaded from app store?
Crashlytics pointed out these crashes as heap corruption. From the logs it rly looks like that there is something trying to free a string that was already deallocated. But if we are able to reproduce this in production, the same issue would have to happen at least in a testflight build. At this point this make no sense anymore.
