I had my xcode working fine,
I updated my phone to iOS 7 and downloaded the latest xcode.
Now if I create an empty app, then run it on simulator,
the app will crash intermittently,
nothing else added... so it will run some times, then will crash on start up,
No error log, only
lldb
and on main.m I see:
Thread 1: signal SIGABRT
What is the problem?
thanks!
Delete the app from the simulator, clean project, restart Xcode and rerun it.
If that doesn't work try to reinstall it again.

App submitted to store one year ago. It worked fine up to iOS 11 but in iOS 12 the app is immediately crashing even without launching. I tried to debug the issue but I couldn't, because before didFinishLaunchingWithOptions, the app crashes and I did not find any error logs.
It is happening in iOS 12 only, working fine with below iOS 12.
How can I debug this issue?
Have you correctly installed your XCode Update? Sometimes you have to install cli
(that is needed e.g. by mtouch if XCode links your assemblies) or other components by hand.
Are you're credentials (certificate) still valid? or otherwise asked: did you build another app since this happens?
Have you set a breakpoint right in you app delegate and step throw until the app crashes? Can you show logs? If you don't have some, than create them by yourself. Do exception handling and log the exceptions. Or otherwise said: More information please.
Using Xcode 5.1 to debug an iOS 7.1 iPad application.
When I build and run my project in the iOS Simulator, the simulator opens and my app icon pops up for a second. Then it looks like the app stops installing and the simulator goes to the home screen. Xcode still thinks it's debugging and it doesn't show any errors in Xcode or the simulator. I can go to my app in the simulator and click it again, but it just crashes. I get the same behavior in iPad, iPad Retina, and iPad Retina (64 bit). Any subsequent tries to run the app in the simulator doesn't even attempt to pop the app icon up until I quit the iOS Simulator and try again. All the usual fixes haven't worked for me yet.
Fixes I've Tried:
1. iOS Simulator > Reset Content and Settings...
2. Window(in Xcode) > Organizer > Delete Derived Data & Delete Snapshots
3. Delete Contents in ~/Library/Application Support/iPhone Simulator
4. Uninstall Xcode and reinstall
5. Clean project and rebuild
6. Restart machine
I'm out of ideas. Is there something I've missed?
Thanks all!
Create another app with the exact same template and look at the app delegates and make sure they are the same.
Example: AppDelegate.h and AppDelegate.m
You might've accidentally deleted an area that helps load the App.
Alright I found the problem. I was playing with how we load our frameworks because we were having other issues before and I left a bad value in our Linking settings.
Here's how I fixed it:
Project > Build Settings > Linking > Mach-O Type set to "Executable"
It was set to "Bundles" before which causes Xcode to package the app in a way that caused ours to break.
Helpful Post: In Xcode project target build settings, What is Mach-O Type?
I get a SIGABRT error in my Xcode-project. The strange thing is, that on another mac the project runs without an error.
I allready did:
clean the project
restarted Xcode and the mac
deleted the app files from simulator
And on both mac's is the same Xcode version.
Have anyone a spontaneous advice for me? :/
Have you checked if the BaseSDK is set to the latest iOS version or not for both macs?
I've got an Xcode project that I've been working on over the past few weeks.
I just made some changes to an embedded framework that I'm working on (recompiled, to be specific) now, however, I am unable to launch the application in the simulator.
The app hangs on "Attaching to [app name]," if I have a debugger on. If I don't have a debugger on, Xcode just says the app has finished running.
There is no icon installed on the device.
Here's what I've done so far:
Restarted
Reset simulator
Clean and build
Deleted derrived data
I cannot install onto a device either, but then I get an error:
Error launching remote program: No such file or directory (/Users/peter/Library/Developer/Xcode/DerivedData/x-gtwuuwmavjonyrcxjmpcletdpyjw/Build/Products/Debug-iphoneos/x.app/x).
Oddly enough, what worked was installing another app in the sim (just launched another project and ran it) and then launching the other app in the sim.
I'm not sure what the issue was, but I tried it on two computers and it was hanging on each, so it was related to the project rather than the simulator. There's an issue to think about...
Is it normal that when i try to test my app it crashes on launch?
I explain.
I have my app that works fine in the simulator. I wanted to try to test it on my iPod Touch 4g.
I built and run from XCode, and that's what happened: the app launches fine (it shows me a black splash screen),but then suddenly it comes back to the springboard,with no reason.
If i open up the app manually,after it crashed,it works without any problems. It happens only one time,just when i build and run,and i don't know why.
How can i do to avoid this? On simulator it works with any crashes,but when i run it over my iPod,it crashes.
Program ended with exit code: 0 // on simulator
The app is likely to be failing to run on the device as xcode is trying to attach the debugger to it but doesn't have permission to do so.
Check your entitlements.plist within your project; you probably have one that has get-task-allow set to NO. This needs to be 'YES' to allow the debugger to attach. (It does need to be 'NO' for adhoc builds though - one solution is to exclude the entitlements.plist file from the debug build.)
