My app has some kind of Zombie problem. (Not an NSZombie problem. Like, a coming-back-from-the-dead problem.)
I first noticed that after a debugging session, when I would go for a run the music on my iPhone would pause every ~7 minutes, and when I'd unlock the device the app name would be flashing red in the status bar as though it had just crashed. Sometimes there would even be phantom sound from the app, like it was still running in the background somehow.
Manually quit the app, continue. Still get the intermittent audio artifacts even though the app no longer appears in my list of running apps.
When I plug back in, this is in the console for each time the app zombified and restarted itself. It looks just like a normal launch of the app! What the? What could be triggering my app to restart itself?

Explanation of the solution: It turned out to be simple - 1. I was shutting down my audio session in dealloc but not in applicationDidEnterBackground. And since I'm using kaudiosessioncategory_playandrecord that seems to tell iOS to restart the app if it crashes in the background.
Now, why is it crashing in the background? ...well, that's my next task.
The app may have a background voip flag set. If it does, the OS will restart the app if it exits abnormally (or when the device restarts).
what audio framework are you using? the iPod app, GarageBand and other audio apps present red flashing in the title bar when audio processing continues after exiting the app. This wouldn't happen with Cocos Denshion I don't think, so you must be using an Apple framework for your audio? The answer likely lies with how it is configured. Apple gives some of its own audio frameworks permission to keep running when in the background so you can have customized music playing, like apps for radio stations, etc.
We will probably need code snippets also as the logs don't tell us what code is executed

I have looked at other thread on same topic but couldn't get any answers there and hence created a new thread.
I am running into subjected error. It started when I upgraded my iPad to iOS 9.3.5 and it happens only on UITextField field. Here are logs but not able to find the root cause. This is occurring in Xamarin.iOS 10.2.1.5 which is latest and greatest.

Has anyone faced the same issue? Not sure what am I going wrong.
This turned out to be an issue with code. But surprisingly code was working fine until I upgraded to latest build.
Lesson learnt, debug the code as you never know what part of code will start failing after you upgrade the Xamarin.
The device is iPhone 6s Plus with iOS 9.2. Using Titanium Studio, when I run in debug mode and stepping through code, the app runs fine. However, when I simply "run" it (device connected to laptop via USB) or install the .ipa file in adhoc distribution, the app crashes as soon as it is launched. There is absolutely no log generated in Titanium when "run". And there is little to no relevant information in Xcode too when the installed .ipa is run. Here is the log from Xcode:

I've searched through other posts, some of whom point to "Javascript Minification" (which I turned off but still got the crash) and some talk about "Fastest, Smallest [-Os]" for Release in Code Generation section of Xcode's Build setting (which I don't know how to control since I'm using Appcelerator Titanium to build the app). Several others discuss specific code issues as revealed by the log. Since I get nothing in the log files that I can tell of significance, I'm not sure where to look.
Any help is appreciated.
UPDATE on March 21, 2016:
It took me a while to figure out the culprit. Here are the steps to reproduce the issue:
1) In Titanium Studio, create a new Mobile App project using Alloy Default template.
2) Run the newly created project as-is to a USB attached iPhone 6s Plus (or probably ANY ios device).
3) Click on the app icon on the device and the app will launch just fine with Hello World on the screen.
4) Now go to the TiApp.xml file and edit it by adding the following parameter:
<property name="appc-sourcecode-encryption-policy">embed</property>
5) Now run the modified project to the USB attached device.
6) Open the app and you will notice that it crashes right after the splash screen shows briefly.
It seems the property above does not work properly. Opened JIRA ticket AC-3389.
It looks like a provisioning issue. Check this thread which deals with a similar error.
If that does not help, please provide some more details like sample code and detailed crash logs (full trace-log). Thanks!
I have a sample App that works fine on the simulator, but crashes on the device. I get the following output on the console from Organizer. It crashes within a short time.
Using instruments, memory leak, I see that the memory usage is about 2-3 mb. Using memory allocations, I see around 8-9mb for memory allocations and nothing in VM tracker.
The console output is given below. Can anyone kindly suggest what to do?

ok, so it seems like everything was fine, I just needed to delete the app from the iPad and reinstall it... pretty weird... !!!
First of all I have no idea what causes the issue and I can reproduce it only after device hardware restart. The app is fine after that.
I use MagicalRecords lib.
"[MagicalRecordHelpers
setupAutoMigratingCoreDataStack]" is called inside "application:
didFinishLaunchingWithOptions:".
After a few inner method calls and
it's freezes for 10–15 seconds.
This is a log from Console where you can see call's details and timings. I just noticed that it's frozen by some strange (for me) low level calls.

I don't really know if users face this problem. But if the do it may probably crash on start for many of them.
I know the problem is difficult to analyze, but if you have at least any related thought or just an idea, please share. Also please ask for any details.
thanks in advance.
So, it looks like iCloud is trying to initialize there. I've heard this has been a problem, however, Apple suggests calling the URLForUbiquityContainerIdentifier: on NSFileManager. This is what's going on under the covers in that method, but it seems that method is also choking at some point...not sure what to do other than in the NSManagedObjectContext category method MR_observeiCloudChangesInCoordinator, comment out the lines that call isICloudEnabled...that is most likely your solution for now :(

But when I run same application on iPad having O.S version 4.3.3(iPad2) it runs perfectly. What is the reason behind this strange behavior & any solution to solve this. Thanks in advance.
your app is crashing because it ran out of memory.
Try using PDF format or PPS (power point slide show) format. That may take some lesser space.
