3. Xcode version used: 13.4.1 (13F100)

To Reproduce Steps to reproduce the behavior:

2. python3 test.py

3. See error:

   % python3 test.py
   Traceback (most recent call last):

   StopIteration

Expected behavior The project file should be written without any change.

That's a disappointing response.
