XCode 4.2 with iOS 5
My app will only crash on the first load on a real device while debugging. If I run it in the simulator, it always works. And every time after the first time on the device itself, it always works fine.
Once I delete the app from the phone, the next launch of the app will crash EXC_BAD_ACCESS but I cannot tell where this is happening even while debugging.
The app failed submission to the app store for this reason. All I can say is that it happens RIGHT before the dialog: "MyApp" Would like to Use Your Current Location
Then when I re-launch it, it works fine.
Here is the crash log, but it doesnt seem to tell us much:

I'm new to buffer overflows and although I believe I get the process, I feel that something is wrong here. I am studying from a book about exploitation and in the example, there is a simple buffer overflow on a 16 bytes string. This is the code of the binary.
#include <stdio.h>
#include <string.h>
void vuln(){
char buff[16];
scanf("%s",buff);
printf("You entered: %s",buff);
}
void secret(){
printf("My secret is 131313");
}
int main() {
vuln();
return 0;
}
As you can guess, the goal is to call the secret function. I compile it on my Mac using Clang with the following arguments -arch armv7 -fno-stack-protector -fno-pie, so no protection and ARMv7 architecture. It runs normally on the iPhone and when it asks for user input I enter 32 bytes, in groups of four like this AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH. When the application crashes I check on iOS logs and I can see that the crashing happens where the Fs start from.
What I expected to see, is that the pc register will have value 0x46464646 for F, but actually it returns 0x46464644.
These are the values of the registers at the time of crash.

Also, I tried with just 40 As and it returned 0x41414140. Why it does not return the input entered as expected?
Thank you
In case anyone has the same issue as me, I found out that r15 or pc should always be divided by 4 in ARM. From the official ARM Documentation:
Note that r15 cannot be used with writeback, and that offset must be divisible by 4
Currently experiencing a problem where the app crashes when you are trying to open it. Any ideas on how to decode the IOS Crash log, i've attached a small section of the crash log below.

Any thoughts on how to determine what the issue is?
I'm trying to build a Xamarin Forms app with an associated App Extension for iOS. My solution structure is like this:
MyProject
\BitThicket.MyProject -- Forms project
\BitThicket.MyProject.Core -- NET Standard 2.0 class library
\BitThicket.MyProject.iOS -- iOS project
\BitThicket.MyProject.Extensions.Intents -- Intents project
Each project was created from a template, and I've made few changes - and the crash happens at startup, so none of my code is reached anyway.
I'm targeting iOS 11.1, and I have a valid signing certificate and provisioning profile set up. I'm able to build the app and deploy it to a device (my iPhone 7+) from Visual Studio for Mac (7.2.2). However, when the debugger tries to launch the app for me, the blank splash view shows and then the app crashes. The debugger never connects. Incidentally, it crashes in the same way when the app is launched manually on the device.
I retrieved the device logs using Xcode, and the crash looks like this:

Does anyone know what causes this? There don't seem to be a lot of direct answers on the Xamarin forums or other places (including SO, unfortunately). I've tried some of the simple things, like restarting Visual Studio for Mac, or delete the app from my device and clean/rebuild the solution, but those things don't seem to help.
In the termination description it sounds like it tried to load mono, but mmap was blocked by code signing somehow - but I don't really understand how. The app builds and deploys to my device, so it seems like code signing is working.
After digging a little further, I found a few examples of problems that seemed similar, and the most common approach factor seemed to be that signing certificates were incorrectly configured. I'm still curious about the underlying reason - the "why" behind the why.
In the end, I found that I had the "Apple Worldwide Developer Relations Certificate Authority" on both the "System" and "login" keychains, as well as configured for "Always Trust", when it should have been only in my "login" keychain and configured for "System Defaults".
Once I corrected those issues, I tried again and I still had the problem. It finally went away after rebooting my mac.
I'm working on a watch App. The Xcode version is 7.3, Swift 2 , iPhone 5 and watch version 3.1.3
First thing Mobile app and watch App both works properly on simulator.The App has two version (English/ Chinese). Now the problem is When I select the english Language for watch, App Works as I needed. But if I change the watch Language to Chinese or any other language then the App Shows a Spinner for long time and then return a black screen. Is anyone facing Same Issue??Please suggest me what is wrong with this app?? Thanks in advance.

One more thing that i forgot to mention is the app works properly on real devices when installed first time but if I uninstall the app and then reinstall it this produce the same issue as mentioned above.
I'm doing an app in Titanium for Android and IOS. When I navigate a lot in the application I have a random exception and the app crashes.
How can I know where is the problem?
The app is a little complex to explain:
It has two windows, first window is for "home" view that is only in portrait mode, and when I click to go to another view, I close the first window, I open another window and I add a view with the content to this window. The content view load the same web view with different url.
The app loads ok and I can navigate for the different views and windows ok. But when I navigate a lot, finally I have a EXC_BAC_ACCESS (SIGSEGV) and KERN_INVALID_ADDRESS
This only happens on device (on simulator it works ok) with iPad os 5.1.1 and os 7.0.2.
This is the log where the thread crashes:

I've also had the log of other threads and information about Binary Images. If it's useful I can paste it.
How can I know what is the cause of the problem and where is the problem?
Thank you very much
You get EXC_BAC_ACCESS because you are trying to access object which was removed from memory. It happens only on device when you navigate to many windows because every window takes some part of memory and when there is no more space for new windows iOS clears old objects who were deleted by you previously.
You can replicate this issue on simulator by forcing Memory Warning pressing ⇧ + ⌘ + M.
To solve your issue you have to store variable pointing to window object which you want to reopen later in some global dictionary.
Finally, I think it was a problem with webview component. I created a web view in each view (I need it to show some graphs) and when I return to home view, I tried to remove it. I think the problem is that you can't remove it completely and it takes a lot of memory.
Finally I solved it creating a webview in app.js and using it in all views changing the url and dimensions.
