Diagnose bad_ex

To diagnose the bad_ex error, you can leverage several debugging and testing techniques discussed in various WWDC sessions. Here are some relevant points and sessions that might help:

1. Using Breakpoints in Xcode:

   • You can set a Swift error breakpoint to stop immediately where any error is thrown. This can help you identify the exact location and context of the error.
   • For more details, refer to the Xcode essentials session, specifically the chapter on "Setting breakpoints".

2. Inspecting Program State with LLDB:

   • Utilize LLDB's backtrace feature to understand the sequence of function calls leading to the error. This can help you trace back to the root cause.
   • For more information, see the Run, Break, Inspect: Explore effective debugging in LLDB session, particularly the chapter on "Crashlogs & starting the program".

3. Handling Known Issues in Tests:

   • If the error is related to a known issue that you cannot immediately fix, you can use the with known issue function to document it and prevent it from obscuring other test results.
   • This is covered in the Go further with Swift Testing session, under the chapter "Tests with known issues".

4. Error Handling in Swift:

   • Ensure that your code handles errors gracefully and that you have tests in place to verify both success and failure cases.
   • Refer to the Go further with Swift Testing session, especially the chapter on "Expectations".

By combining these techniques, you should be able to diagnose and address the bad_ex error more effectively. If you need more specific guidance on any of these points, feel free to ask!
