Can I understand that this part is not the really point where my app crashes?

Answer 1

It's not a crash, it's an abort due to an exception. It means that your application is passing bad data to a system routine and the routine is saying that it's bad and can't continue, so it's killing your app. The console should show something about what went wrong. One common exception that can occur is attempting to get the n + 1st object from an array with only n objects in it. (For example getting the 5th element of an NSArray when there are only 4 elements.) The console will have a message that says just that. So check the console to see what might have happened.

Do you mean, how did I find the error message? If so, it's in the console window in the debugger when running your application in Xcode. It may also be in the log file you got the stack trace from above. If you download the console logs from the device, it should also be there. – Kneehigh

I got this crash log from some device, but I don't know what does it means. So how did you know it is an "abort do to an exception"? And how can I fix it? – Farley

Because the top of the stack says pthread_kill, it means that the program or an OS routine that the program called told the OS to kill the app. A little further down, you can see the call to abort, which indicates that the program, or an OS routine specifically attempted to abort execution. Further down, in stack frame 7, you can see objc_exception_rethrow, which means that an Objective-C exception was thrown. The way to fix it is to find out what the exception is by making it happen on another device (or simulator), or getting the full console logs from that device. – Kneehigh

I am sorry, but this is the full console log I got from a device. Do you means that I must see the crash when I run it durning debugging? And is it helps me to find the crash in another device? – Farley

Is the device normally connected to a Mac? If so, you can open up Console.app, click "Show Log List", and in the list of logs, under "Files", twirl open "~/Library/Logs" (assuming it's the user who owns the device that's logged in), then twirl open "CrashReporter", then scroll down and twirl open "MobileDevice". You should see a list of all the iOS devices that user has plugged into their computer. You can then select the appropriate one, twirl it open, and you'll see all the logs for various apps including yours. – Kneehigh

So you're saying the app is aborted because some of my code is wrong? or it's natural? What's difference between crash and exception? – Mervin

It usually happens because your code is wrong. It can happen, for example, if you have an NSArray with a single element and you try to access element #2. The difference is that a crash happens when the OS decides to abort your program because it did something illegal like accessing memory that doesn't exist, or that your process doesn't have permission to access. An exception occurs when you pass a library, function or method bad data, and that library, function, or method decides it can't continues and asks the OS to abort the process. (Some types of exceptions can be handled, but some abort) – Kneehigh

Answer 2

Solved !!

I have solved this issue : replace below files files from your project file(if you have backup of your project):

1. pods
2. projectname.xcworkspace
3. podfile.lock, podfile
4. add pods in podfile if any pod missing and install pods
5. Build your project and run

Please get project backup in zip this will help to solve this error.

Answer 3

I had deleted my Main.storyboard and had replaced it with the storyboard from another project. My solution was to delete my project and recreate it.
