c# - App rejected twice but cannot reproduce the issue on iOS 9.2. I need help identifying it

I cannot reproduce the issue on any iPhone and iPad, all builds on Debug, Release and even the ad-hoc build installed with iTunes work just fine. This is an update of an already existing app. The only things added from the previous version are Notifications using Azure Notification Hubs and a version check. I am using the latest version of Xamarin iOS to create the app

The supported Architectures are ARMv7 + ARM64

I have tried:

  • Running the zombies instrument
  • Minimizing startup load

Part of the crash log is here but i cant make anything of it

Crash Re Symbolication is process to find exact crash issue.

Just follow given steps to counter your crash issue. To get your symbolicated logs from Crash logs you will need following files:

  1. AppName.app?—?Application file (Executable)
  2. AppName-dsym.dSYM?—?dSYM file, generated by XCODE when actual .app file complied
  3. AppName-Crash-log.crash?

enter image description here

Follow all the steps carefully and then check crash logs you will find exactly where it crashes the app.

Now follow below given steps :

  1. Move all the above files (AppName.app, AppName-dSYM.dSYM and AppName-Crash-log.crash) into a Folder with a convenient name wherever you can go using Terminal easily. Simply create MyCrashReport folder on desktop and add all three files in it.

  2. Go to the path from following whichever is applicable for your XCODE version :

Xcode 6

/Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash

Other then Xcode 6

Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash

Or

Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash

XCode 7.3

/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash

  1. Copy symbolicatecrash file from this location, and paste it with above three files in MyCrashReport folder.

enter image description here

  1. Open Terminal, and CD to the MyCrashReport Folder.

  2. cd Desktop/MyCrashReport?—?Press Enter

  3. export DEVELOPER_DIR="/Applications/XCode.app/Contents/Developer"?—?Press Enter

  4. ./symbolicatecrash -v AppName-Crash-log.crash AppName.dSYM?—?Press Enter

Its done!!! Now Symbolicated logs are on your terminal and find out error or crash in it.
