Lost Framework - UIKit.Framework

[AeroJet]

I am building an app that uses the UIPicker Control. I Had the app working and then left the project for a few days. I came back to work on it and suddenly it doesn't work - I get a run time error when I scroll the picker.

Clearly I did something, but as I am new to the iPhone programming and OSX world in general, I am not sure what I could have done. The app (and I built a new one just to test the picker control) build with no errors or warnings. The simulator loads the app, displays the picker and the content. I have some console logs print and they appear to be fine.

Once I try to scroll the picker, it starts to animate and then locks up. I get a debugger dump in the console with these warnings:

Unable to read symbols for "/System/Library/Frameworks/UIKit.framwork/UIKit" (file not found).
Unable to read symbols from "UIKit" (not yet mapped into memory)

Unable to read symbols for "/System/Library/Frameworks/CoreGraphics.framework/CoreGraphics" (file not found)
Unable to read symbols from"CoreGraphics" (not yet mapped into memory)

Those files indeed do not exist, on the machine. I removed the Developer directory and reinstalled the SDK with no success.

What did I do and how can i fix it? Is it a setting in Xcode? It shows up in my project list, both programs compile successfully but they don't work. It seems to me that the program shouldn't compile if the header and other files didn't exist? Further, how is the app able to load, build and display the picker if the files don't exist? All of those methods are part of the same framework - right??

I even had an old working target app in the simulator that I was no longer working on that has stopped working. Same error.

Thanks in advance for the advice. I am very excited about the iPhone dev, and look forward to contributing in the future (when I'm not such a newbie!)

These lines in the output log are "normal", in the sense that they're not indicative of a missing Framework. I'm not entirely sure what they mean, but I believe it's just gdb saying that it can't find symbolic information for those libraries. () Anyway, if a Framework was missing, you'd be unable to link your application, and what you're describing is clearly a run-time crash. So... what did you change between the time it was working and now??

I agree. I have no clue what I changed. (I have been trying to resolve this many days now.) But I figured when I wrote a new test program, it would should work - but it didn't. Further why did a working app in the simulator stop working? That makes no sense to me.

And I never rececied these errors (or log warnings) in the console before.

I guess I am really good at breaking things!

Is there a way to cleanly uninstall the development software so I can cleanly reinstall it?

Anyway, thanks for any help.
