My IPhone app is suddenly giving a SIGABRT error message when I attempt to run it on my iPhone, before even the first line of the application delegate is reached. It runs fine in the simulator, and even restoring previously working snapshots give the same error when I attempt to load the application on the device.
I fiddled with the Product Name build setting and the data model prior to the problem occurring, but as mentioned, old snapshots that ran fine now won’t load, suggesting that the problem isn’t in the code.
I have tried restarting xCode, the computer, the iPhone and deleting the app but the problem is still occurring.
I am sure that the problem lies with the device
Any ideas what the problem might be or how I can fix it?
Taking on Till’s suggestions I reinstalled iOS (well, actually I updated it to 5.1) and everything is working again. Thanks for the advice. I’ve no idea what went wrong, but at least its working again now!
