I am hoping someone has had these errors and knows how to fix it.
This is the console output in Xcode 5 b4 that suddenly appeared:
Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.0.sdk/System/Library/AccessibilityBundles/CertUIFramework.axbundle> (not loaded)
I had this problem when using the KIF testing framework as imported via CocoaPods. Removing this pod resolved the problem. KIF uses some private frameworks for accessing UI elements so this seems like a reasonable cause
If the reset of the simulator does not solve your problem try the following:
In Terminal type:
Delete your "iPhoneSimulator7.0.sdk". Then reinstall Xcode. Reinstalling is really fast because just the missing folder gets replaced. This fixed it for me.
Temporary workaround: click iOS Simulator > Reset Content and Settings... and run again.
This error message may reappear at random. For me, it happens when I launch a different application. There are several threads in Apple dev forums and in StackOverflow about this problem, but none have a definitive answer. This seems to be a SDK error.
Updated: February 10, Xcode 5.1b5.
