My app is in app store which supports iOS 7.1.2 to iOS 8.4 and it is working fine till 8.4 version. When I tried to run the same app on iOS 9 beta 5 its getting crashed.It was working fine in iOS 9 beta 4. After debugging I found that the crash is due to the custom font we have used in our app. Is this the problem with iOs 9 beta 5 ? What should I do to support my app on iOS 9.0 main release which will be expecting in a week.
Below is the stack trace of crash

Today i find a bug in my app relate to UIWebView, there are two case for it, the url i request is https://estore-cn.pandora.net/Bracelets-1/
When I use UIWebView to show a web page, and I exit that page, the webView's dealloc been called, but the UI thread been blocked, and several minutes later it recovers.
This is the thread stack here when I press pause program execution button in Xcode.

I am getting a rather peculiar issue of EXC_BAD_ACCESS. In an inventory based app, when creating a receipt..the app works fine if the vehicle already exists in the database and crashes when a receipt with new vehicle is being viewed.
I tried to run the app with NSZombieEnabled but nothing gets logged onto the console when the app crashes except lldb.
So the question is that if NSZombieEnabled does not work, how do I determine what is causing the crash in an app.
I am running Xcode 5 (latest version) for development.
Edit On running bt in command prompt..here's the backtrace I get
(lldb) bt

Thank you for your help in advance!
When I click on any button my app crashes. It throws a lldb run time error. I printed the backtrace:

What does it mean?
This is your problem:
Foundation`-[NSObject(NSKeyValueCoding) setValue:forKey:]
because after this, is raised an Exception:
CoreFoundation`-[NSException raise] + 12
You are trying to set a value for a key in your object that could not exists or has some other problem.
P.S.: Update your answer with some relevant code so I can update my answer with more explanations.
I developed an app in Xcode 5. Until now I only tested it on a device running iOS 7. I tried running it on another device with iOS 6 but it crashes on launch in the main function without any error message in the console. The deployment target is 6.0 and I've chosen Standard architectures(armv7, armv7s) in the Build Settings.
I also checked the code for methods available only for iOS 7. Could it be that I accidentally skipped one? As for as I know I should get an error message if it doesn't recognise the method.
I'm not a newbie on iOS development, but something is skipping my attention. Do you have any idea what it could be?
I would really appreciate your help. Thank you.
UPDATE:
This is it... Could it be something in the plist...?
I finally got to the bottom of this problem thanks to "OC Rickard". Writing 'bt' in the console, this was the output:

I had a font declared in the plist file which had .dfont extension. Apparently iOS 6 didn't like this. Thank you "OC Rickard", and thanks to all of you guys for taking interest in my problem.
