iPhone simulators crash on app launch

Question

I'm having some issues with the iPhone simulators after upgrading to Lion and XCode 4.1. When I launch the simulator for 4.0, 4.1 or 4.2 (which I restored from Time Machine), I get an EXC_BAD_ACCESS error pretty much immediately on this:

0x003c23dc  <+0012>  call   0x3c23e1 <__springboard_unimplemented+17>

On 4.3, I also get an EXC_BAD_ACCESS error immediately, on objc_msgSend, and from what I can tell, it's happening before the application even launches.

I've tried cleaning the targets to no avail, and NSZombieEnabled doesn't seem to help.

The app runs perfectly on my iPhone.

EDIT: Uninstalled and reinstalled Xcode, didn't help. A blank new project runs fine. After setting some breakpoints, it looks like it's failing on this line in main.m (which isn't very helpful):

    int retVal = UIApplicationMain(argc, argv, nil, nil);

EDIT: As requested, here's the thread apply all bt full:

For the 4.2 simulator, this is repeated ~5800 times, with a different memory address each time:

which is followed by stuff like this:

EDIT: Reinstalled the SDK, didn't fix anything.

Answer 1

I ran into this as well. I fixed it by removing my /Developer dir, installing Xcode 4.1, then installing Xcode 4.2, THEN installing the latest iTunes 10.5 beta. Haven't had issues since.

Answer 2

Firstly you can reset your simulator & quit your Xcode. After that you can delete the Application Folder in iPhone Simulator & also delete all derived data from /Library/Developer/Xcode/DerivedData. Then open your project & check whether any framework is missing or not according to your app functionality.

Answer 3

Ok, so after weeks and weeks, I finally found the solution: fixing my linker flags according to this comment: EXC_BAD_ACCESS when copying or retaining Block

Essentially you change -weak_library /usr/lib/libSystem.B.dylib to -weak-lSystem.

I had originally added this because Urban Airship required it.

Answer 4

You're missing some core functionality for the simulator. Springboard is the name of the app-launcher "desktop" for iOS, and your simulator system seems to think it's unimplemented.

__springboard_unimplemented ()

This discrepency would explain why you're having trouble on the simulator, and not your phone.

I would suggest a full removal of Xcode and the iOS SDK, then reinstall fresh from the App Store.

EDIT: Some of my Googlings:

• https://discussions.apple.com/thread/3028002?start=0&tstart=0
• http://twitter.com/#!/gparker/status/16728366321
• http://pastie.org/2271247

The last one was buried deep within the confines of Apple-Developer-only territory. It's a text-dump from a forum, so it's not formatted particularly well, but it looks to be the most promising. This looks like the bottom line:

Your app died because something called abort(), as shown in the Application Specific Information. The backtrace shows that abort() was called by __springboard_unimplemented(), which means you're calling a function that is present in the simulator but may not be on the device. That function is mcount_L1(). Calls to mcount_L1() come from profiling tools. To fix this, make sure you have "Generate Profile Code" unchecked in your build settings.

Answer 5

You said you upgraded to Lion. Did you install the Lion build of Xcode or the Snow Leopard one? This looks to me like you need to install the Lion build of Xcode on Lion.

edit: The fix is in the comments, putting it here. Recreating the project file using the fresh lion installation and importing the existing source code got things going again.

Answer 6

The answer to your problem lies in what you have written: (which I restored from Time Machine).

You are using a restored version of the Simulator that do not match your Xcode 4.1 installation.

Using any Simulator not part of the installed SDK is done at your own risk.
