Iphone-SDK "unable to read symbols error" when linking to IBOutlet in tab based app
<p>I built a very simple tab based app with 2 tabs, each tab tied to its own view controller.  </p>

<p>Straightforward so far.   I then create a simple IBOutlet on my 2nd view controller like so</p>

<pre><code>#import &lt;UIKit/UIKit.h&gt;


@interface bViewController : UIViewController {
    IBOutlet UITextField *aField;
}
@property (nonatomic, retain) UITextField *aField;
@end
</code></pre>

<p>then i synthesize it in my .m file, then i go into my xib, drag a text field onto the view and then set the files owner to 'aField'. </p>

<p>Very textbook so far. </p>

<p>It builds, but when i run it and select the 2nd tab (which shows the view where i've linked the UITextfield IBOutlet), it throws this error.  </p>

<pre><code>warning: Unable to read symbols for "/System/Library/Frameworks/UIKit.framework/UIKit" (file not found).
warning: Unable to read symbols from "UIKit" (not yet mapped into memory).
warning: Unable to read symbols for "/System/Library/Frameworks/CoreGraphics.framework/CoreGraphics" (file not found).
warning: Unable to read symbols from "CoreGraphics" (not yet mapped into memory).
</code></pre>

<p>which is VERY ODD because this only started happening recently.  Any clues?</p>

<p><strong>UPDATE:</strong></p>

<p>I'm beginning to suspect a config error rather than a syntax error because these are stripped down samples i created just to demonstrate the problem.   This fails only when i create a tab-based application.    </p>

<p>if i do the EXACT same thing in a view-based application, it works fine. </p>
