libc++abi.dylib: terminate_handler unexpectedly threw an exception - 0 stack trace iOS7 / iOS 8

I got the same error and a "clean" didn't resolve it.

It was caused by my internet testing flow, I check to see if WiFi is connected but not if that WiFi has an active internet connection that can resolve a supplied URL. It performs a dataWithContentsOfURL: that will ultimately fail. A similar thread made this suggestion to this question here by user Keith that helped me identify the problem -- which was to add breakpoints to C++ exceptions.

To enable -- click your breakpoints view and the very bottom click the '+' to add a breakpoint. Set it up as follows and the stack trance will be more meaningful.

Clean the project. Check each constraints and remove the corrupted one. Clean project again, it should works.

This can be caused by an outlet that is no longer existing (might have been renamed or removed).

Here is a tip on how to check outlets: Select the container view of the suspected outlet, pay attention to "!" marks in the connections inspector.
