all. I’ve been banging my head for a few hours because of this problem. I have a universal project that’s a mix of iPhone and iPad projects. I put these codebases together into the universal project and, after a lot of “#if __IPHONE_OS_VERSION_MIN_REQUIRED >= 30200” checks, got the project to run in both the iPhone (OS 3.0 to 3.1.3) and iPad simulators. After doing a more finagling with the project settings of external libraries that I load, I got the app to load on an iPhone (which runs OS 3.1.3).
However, when I run the app on my iPad, I get an immediate SIGABRT error. I’ve tried running it under Debug, under Release, with Active Architecture of both armv6 and armv7. I’ve checked and double-checked that the app has the right nib files set up (but, again, this app runs fine in the simulator). I’ve gone through the external libraries I’m using and set them up to have the same base SDK (3.2), same architectures (Optimized (armv6 armv7)), the same targeted device family (iPhone/iPad), and the same iPhone OS deployment target (iPhone OS 3.0).
So, to summarize… I have a universal app that works in the simulator for iPhone and iPad, runs on an actual iPhone, but doesn’t run on an iPad. It doesn’t get far on the iPad — there’s an immediate SIGABRT error that stops execution. Help??
Edit Following Jason’s suggestion below, here’s the stack trace of my app:

As you can see, it doesn’t get out of the main function in main.m.
This looks like you have some connections in the main Nib-file which points to non-existing outlets in the code being loaded. Make sure you load a Nib-file which match the platform and which is in synch with the code being loaded.
If you are removing some outlets in your code by means of
#if __IPHONE_...make sure you don’t have the Nib-file trying to reference this outlet.
