HI there,
Some users of my application have reported me that my application is no longer working. It closes just after launching it.
I have been trying to identify the crash for days with no luck using builds debug and release and testing it in several devices. This morning I was surprised when I was able to reproduce the problem by generating a AdHoc version and installing it on my iPhone.
I have already tried to remove all the custom configurations and recreate them using a copy of the release version but it did not work.
I got this error below when I was running in the simulator and the crash reports also points to the same place...
Detected an attempt to call a symbol in system libraries that is not present on the iPhone:fwrite$UNIX2003 called from function -[My7zipExtract extract7zFile:]
So, my question is: What is the difference between build Debug/Release and Distribution (App Store/Ad Hoc). I have double checked everything and the only difference are the certificates.
Any help is appreciated.
Many thanks
I'm having precisely the same problem right now. I copied my Debug Xcode configuration to create the AdHoc one, adding entitlements and changing the certificate.
Doing good old printf-debugging ;) i found that the c++ constructors seem to be called differently / not called at all on the iPhone when using the AdHoc build.

Yesterday i was testing my app in the iOS simulator and everything was working fine. I then decided to run the app on my iPhone and i got the error unable to install application, Unknown error occurred this has happened before so I cleaned my build folder (as this has fixed this issue before) however, the same error occurred. I then ran the app in the iOS simulator again and now i get the error Unable to run app in Simulator, An error was encountered while running (Domain = LaunchServicesError, Code = 0). I find this very weird as i didn't change anything besides trying to run the app on my iPhone. I have tried every solution given on this post and still no luck.
I'm sorry if my question doesn't contain much detail but as I said I didn't change anything and it was building and running fine a minute before plugging in my iPhone and trying to run it on there.
Any help would be much appreciated.
edit
I tried running other projects (with and without extensions) and they are working on both simulator and iPhone, therefore the problem must be within my project. (my project does have a today extension)
In that kind of cases I usually :
Product > Clean
Close xCode
Delete the Derived Data (in ~/Library/Developer/Xcode/DerivedData subfolders)
Delete the app on the iPhone
Reboot the iPhone
Restart and rebuild
I had this problem. In my case, it was caused by the Build value being blank. After putting a value there, and resetting the simulator once more, the issue went away.
I had the same problem and checking the system log carefully helped me to identify a coliding library that was causing this error. You can also check this answer if you are using extensions.
Generally it means there is a problem with the build, it may be due to old cache (solved by a clean build) or a project definition error (missing library, bad definition in info.plist, etc).
In my case it happened only on iOS 8, turns out that my widget had the wrong bundle ID.
Recently, after upgrading to Lion and Xcode 4.2.1 I am getting this error when trying to run my app on my iPhone 4S:
"The application bundle does not contain a valid identifier."
My identifier is indeed valid, and I have been able to run my app with this identifier earlier.
The problem might appear when I change computers.
I have two computers that I am using to code my app, and I am using Dropbox to keep track of my files.
Restarting XCode, my mac and my iPhone does not work.
Cleaning the target and rebuilding does not work.
The only thing I have been able to do to fix it is to create a completely new project and moving my files. This made things work until I swapped computer. Now I am in the same trouble again.
Any idea? Anyone?
Three suggestions:
Check that your developer key is in both computers
Did you try to update the project? There is a strangly-named key in the middle bottom under the project's properties. Try this.
I had similar issues. I found that some things weren't updated when I updated osx and xcode. To get out of the situation, I would suggest creating a new project and copy paste code, files and build settings. This might seem stupid, but you know apple is not good at creating IDE's. You might just get your self lost in the undocumented settings.
I've imported an iPhone app that I have developed for iOS and am now maintaining it. I've came across a couple of bugs when trying to add to the iPhone's calendar, which I'm happy to try and sort out myself with a bit of debugging.
One problem is that when I go to run the application on the iPhone simulator, it seems to run an older version of the app than the one I am running. I've removed and added another button since then and the old button is still showing when I run it in the simulator. However, when I compile and run this on a device, it loads the correct version and displays the correct version number in the 'about' view.
But... my main problem is that it doesn't seem to debug on the device properly. The app actually works fine except for the calendar problems, but if I put a few breakpoints in so I can see exactly where this is going wrong, it just doesn't seem to step through! The app pauses, and Xcode says the app has paused! I can press step over and continue execution etc and it appears to work, but I can't see it stepping over the code, nor can I hover over variables to see their values.
I've tried reinstalling Xcode multiple times (I did have a problem installing an older version, so I had to wait until the next version was available before Xcode would install).
The stress is: Today is my last day at work, and I'd really like to get this app ready for iOS 5 before I leave.
Has anyone seen these symptoms before? Is there a debug setting that I've missed? Or is it a corrupted installation?
I wish I could help people a bit with more information, but I don't even know where to start looking here. Any code I can post? any settings? (not too familiar with this, I'm a .NET guy usually).
Thanks!
Sorry you're going through a tough moment there Connell; as you said you're not too familiar with all this, I'm laying down a few steps which might help you out. Some are pretty basic, yes, but I've resolved to these steps myself several times when I've encountered similar scenarios;
If you're testing on the simulator, do a 'Reset Content and Settings' from the 'iOS Simulator' main menu. This will remove all old data and settings and give you a clean start.
Do a 'Clean All Targets' from the Build menu. Then go to your physical project folder and delete the Build folder from it altogether before starting to build again.
Restart both XCode and the Simulator (and your Mac too if possible)
Make sure the mode is set to Debug and not Release or Distribution
Even on the device, remove the old app before putting the new one in, and restart it for good measure.
Delete all Provisioning Profiles from the device and install just the one you need.
On the code;
I've noted that the app appears to 'pause' like this a couple of times when I had accidentally created an infinite loop in the code. Double check to see whether there's something which may cause this.
Unless you haven't already done so, throw an NSLog or two in there to see if its really not being executed beyond the breakpoint.
I've had the exact same problem with a project that I started on xcode 3 and then switched to xcode 4. What fixed it for me was changing the compiler in the project settings.
The default compiler up to xcode 3 was gcc, while the default compiler on xcode 4 is LLVM gcc.
Now, I don't know exactly what's the issue that gdb could have with LLVM gcc, but switching the compiler back to gcc in my project settings and doing a clean build fixed my debugging issues.
Might be worth a try.
Have you checked which debugger is being used GDB or LLDB? Select Edit Scheme from the Product menu, and see what the Debugger setting is under the Debug scheme. You could try switching between GDB, LLDB, and None and running in between.
I really combed this site and others. I read and re-read the related links here and the Apple docs. I'm sorry, but either I am obviously missing something right under my nose, or this Apple profile/certificate stuff is a bit convoluted. Here it is:
I have a product in the App Store.
I have updated it several times and users like it.
My development profile recently expired just when I was improving the app for its next release.
I can run the app in the simulator.
I can compile and put the distribution build on my iPhone just fine.
I went to the Apple portal and renewed the development profile.
I downloaded it and installed it in Xcode.
I see it in the Organize window.
I see it on my iPhone.
I CANNOT put the debug build on my iPhone to debug or run with Instruments. The message is that either there is not a valid signed profile or it is untrusted.
I subsequently tried to download and install the certificate to my Mac's keychain.
Still no success.
I checked the code signing section of Project settings and also for the target and the root. All appears to indicate that it is using the expected development profile for debug.
Yes, I had deleted the old profile from my iPhone, from the Organizer. I cleaned the Xcode cache and all targets. I have done all of this several times and in varying sequences to try to cover every possibility.
I am ready to do anything to be able to debug with Instruments in order to check for leaks or high memory usage. Even though the distribution compile runs fine on my iPhone and plays well with other running processes, I will not release anything without a leaks/memory test.
Any ideas will be appreciated. If I missed something obvious, please forgive me - it was not due to just posting a question without searching for similar postings.
Thanks!
All problems solved! I am very happy this all happened because I learned so much about Xcode, keychains, certs and provisioning. Unfortunately, there is not a simple answer. Here are the highlights:
I needed to recreate the ad-hoc profile and install it on my device. (That was MY BIG oversight and the reason the dist build no longer ran on my device.)
Between the very first time I created my profiles and the date my development profile expired, I upgraded to the 3.1.3 Xcode SDK.
It seems that this now means you need 2 entitlements files; a debug version with the get-task-allow checked and a distribution version with get-task-allow unchecked. Each need to be set in the respective settings.
In Project settings, I needed to set both my working directory and intermediate directory to the build product directory.
BIGGIE - I had to double click on the target and reset the appropriate code signing profile. There was an old profile name still there for some reason! Now, I can debug, and drop my distribution on my device without a hitch.
So, in summary, I believe that my original problem (not being able to debug after renewing my dev profile) and the problem that resulted from all my efforts to fix the first were caused by:
the fact that I upgraded to 3.1.3 during my dev cycle
my own oversight (I apologize to Apple for my criticism)
an Xcode quirk (the old profile name hanging around in target settings).
I hope this helps others. The best advise I can give is to take a day off and then create a new empty project, going through the same process step by step.
Thank you all!!
Try re-creating your development mobileprovision file on Apple's site. Be sure to delete all old copies from Organizer (including those on the iPhone itself).
I set up all my certificates and keys today and am trying to run my project on my iPhone.
I'm encountering this strange error:
Your mobile device has encountered an unexpected error (0xE800003A) during the install phase: Verifying application
Poking around the Apple Developer forums, I've attempted to set new certificates and provisioning profiles as well as editing Info.plist, but no matter what I do I can't seem to run the app on my device.
The only think I can currently think of is that my project name in Xcode differs slightly from my development provisioning profile (it uses a question mark), but I've named it according to Apple's conventions: com.mycompany.myapp, so I'm unsure if that's the problem.
Any ideas?
Edit: I've hard restarted the phone, rebooted Xcode, cleaed my targets, set up a new wildcard App ID and respective provisioning profile and still nothing. Any other ideas?
It turned out that I had 2 certs in keychain that were simultaneously overwriting each other! I hope this helps people in the future.
You should create a wildcard app ID; com.mycompany.*. That may help.
I've encountered this on many occasions. What i do is clean all targets, shut down xcode, and hard reboot my phone.
This is a different error than the more common problem of getting the cert wrong...
Restore the phone (using the XCode Organizer to reload the latest OS), to be safe do not restore from backup when you sync with iTunes the first time (it'll still keep your number when you sync even if you don't use the backup). I've had to do this a very few times, the last one was when it was in the middle of deployment when I unhooked the phone from the cable (had to answer a call).
Try the reboot (of the phone) first, hooking it up with XCode off. But if that does not solve things, restore is the way.
The console tab in the XCode Organizer sometimes gives helpful hints as to what happens during the install phase. In one case my problem was my app already existing on the phone. I deleted my app and the install succeeded.
Regardless, it looks like a lot of error messages are bundled into this one cryptic message and to really diagnose what is going on, I found the Console tab very useful...
One other thing to try is reinstalling the iPhone SDK. I ran into an error like this when I first got my developer key and this was the only way around.
Just want to say to everyone, when you go to edit Targets-> be sure to set "configuration" in the top left corner to "All Configurations" or the correct config you are building for (Debug or Release). You might think you have things set correctly but it will be for the wrong configuration.
I've seen that error on a correctly provisioned device that has had success installing apps from XCode before, and I've had luck restarting the device and trying again. Maybe that will help.
Try running in Release mode instead of Debug. I have a working project with this problem. No idea what the issue was, but running it in Release mode works, but Debug mode produces the error code.
I have a support ticket open with Apple dev support for the same problem, and (FWIW) I'll post their recommendations if and when they can get my toolchain working.
Try this: (source: http://ephemera.lifewithalacrity.com/iphone_development/)
Even though this is supposedly only for Distribution builds, it helped me to be able to install my Debug version on my iPhone again, after it mysteriously broke yesterday.
"just triple check that all the code signing in your project properties are clear or default"
Note, this is the PROJECT properties as opposed to the TARGET properties. I set my Code Signing Provisioning Profile back to the default and removed the Code Signing Identity string.
