I have an iPhone app which is crashing on iOS9 devices only after being released through TestFlight or the App Store. The build specs are:
Deployment target 8.1
Base SDK: Latest iOS (iOS 10.1)
Before I post the crash logs I wanted to mention that this app has been on the app store for the past 2 years and has never had issues. We have done 3 updates to the app store this year with 2 of those being after iOS10 was released and there were no issues with iOS9 devices.
The odd thing is that we are using Crashlytics and it has reported over 600 crashes, each one of those a singular crash that points to either an internal apple framework or private API. I have got an iOS 9.2.1 device that is also crashing that I have pulled the logs from. They are starting to follow a trend however I need some help deciphering the cause of the crashes.

The last two crashes look like they may be failing on finding an image asset... However because I cannot get this to replicate in debug mode or any form of "run" from Xcode I am stuck.
Appreciate the help community!
The same problem occurs to my app. It crashes in iOS9 on release only through TestFlight or AppStore.
See the accepted answer https://forums.developer.apple.com/thread/60919 . It works for me,and I fixed the bug.
How to resolve "ERROR ITMS-90682: Invalid Bundle - The asset catalog at 'Payload/XXXXX/Assets.car' can't contain 16-bit or P3 assets if the app supports iOS 8 or earlier."
With Xcode 8 GM, this error will occur if you include 16-bit or P3 assets in an app submission targeting iOS releases earlier then iOS 9.3. If your app requires wide color functionality you must change your Deployment Target to iOS 9.3 or later. If your app does not require wide color functionality and you wish to deploy it to older iOS versions then you should replace all 16-bit or P3 assets with 8-bit sRGB assets. You can find 16-bit or P3 assets by running “assetutil” on the asset catalog named in the error message from iTunes Connect. The following steps outline the process:
Create an Inspectable .ipa file. In the Xcode Organizer (Xcode->Window->Organizer), select an archive to inspect, click “Export...", and choose "Export for Enterprise or Ad-Hoc Deployment". This will create a local copy of the .ipa file for your app.
Locate that .ipa file and change its the extension to .zip.
Expand the .zip file. This will produce a Payload folder containing your .app bundle.
Open a terminal and change the working directory to the top level of your .app bundle cd path/to/Payload/your.app
Use the find tool to locate Assets.car files in your .app bundle as shown below: find . -name 'Assets.car'
Use the assetutil tool to find any 16-bit or P3 assets, in each Assets.car your application has as shown below. : sudo xcrun --sdk iphoneos assetutil --info /path/to/a/Assets.car > /tmp/Assets.json
Examine the resulting /tmp/Assets.json and look for any contents containing “DisplayGamut": “P3” and its associated “Name". This will be the name of your imageset containing one or more 16-bit or P3 assets.
Replace those assets with 8-bit / sRGB assets, then rebuild your app.
Update: If your Deployment Target is set to either 8.3 or 8.4 and you have an asset catalog then you will receive this same error message, even if you do not actually have 16-bit or P3 assets. In this case you will either need to lower your Deployment Target to 8.2, or move it up to 9.x.
Release crashes (crashes that happen on builds sent through the App Store or TestFlight) can be tough to nail down. I had one which was crashing on NSArray's containsObject: function, and could not reproduce it myself, or so I thought.
I did the following to reproduce the bug.
Went to Product -> Scheme -> Edit Scheme...
Clicked on the "Info" tab for my standard debug scheme
Changed the build configuration from "Debug" to "Release"
Rebuilt and ran the project
In some cases, this is not enough to reproduce a release crash. I did the next steps to reproduce it.
Unchecked the "Debug Executable" within that earlier Info tab on the scheme
Cleaned my project and build folder (Command-Shift-K and Command-Alt-Shift-K respectively)
Rebuilt and ran the project
Here is what it would look like on my configuration if I needed to do the same thing.
Once you are able to reproduce the crash (hopefully you can reproduce with logs), try your usual debugging methods to see where it is crashing. Play a sound when something executes, comment out lines, etc.
I unfortunately can't know your exact crash, though this method above helped me reproduce an issue 90% of our users were having and I wasn't, simply because I was building on debug before.
I am using core plot library Release 2.0 downloaded from https://github.com/core-plot/core-plot/releases in MAC application to generate the bar graphs. When i install application on OSX 10.8 and 10.7 application crashes. It works well above 10.8.3. The linker flags is -ObjC and -all_load is already set in build settings.
I am getting below issue in logs. Can any one please look the issue and help me to resolve.

Dashboard suggests that the crash has happened at forgetKeylessKrollObjject method. From the stack trace it seems that during a view removal, this indicent happened. There are many places in the code where we have added and removed view. As there is no definite place defined in the log and nor we have the test case, we went through the framework code and saw that there is no null handling inside the method as TiProxy.m --> krollObjectForBridge function can return nil.
If anyone from the community has received such report and been able to resolve it. Please do let us know as there is no way to map this stack trace back to the JavaScript code.

Somebody has an idea, please help.
By the crash log we see that, inside -[Visionaries_ViewController connection:didReceiveResponse:], you are calling the method setLength: on an object that does not have that method.
Can be a memory or logic problem. Please provide more info.
