Assertion Failure

[lukeirvin]

I've never gotten an Assertion Failure before. I've researched it but haven't found much luck. I've tried cleaning my project, renaming the file, even rebooting my machine and starting over. Still getting this error. Here's what's in the detail. Any suggestions?



Assertion Message: An uncaught exception was raised.

Thanks much!

You might have changed your build SDK from iPhone 4.0 to Mac 10.6 for some reasons. Do the followings:

Select Project File > Get Info > Build > Base SDK
Select Target > Get Info > Build > Base SDK

Let me know if it works.
