I just recently started back on working on developing iPhone apps. I downloaded Xcode 3.2.2, and I am having issues with both my apps & sample code from apple.com. When I try to build & run the app, I receive the following error: I have tried the various versions of the simulator iPhone OS all with the same result. I am not trying to build & run on a device - just the simulator. I have I have also completely removed Xcode and reinstalled. I haven't been able to find any other things to try. Has any one else encountered this behavior? Thanks in advance!
