I tried to install Cartopy with Carnets Plus in my iPad pro, but failed.

Hi, Cartopy has several modules written in C and Cython, so it cannot be installed by the user, because there isn't a C compiler available. It is on the top of the TODO list, so it should be in the next major upgrade. We have geopandas available on Carnets-with-Scipy (which is not the same, but has a significant overlap in features with Cartopy).

Hi, The current TestFlight version of Carnets-with-Scipy has Cartopy installed: https://testflight.apple.com/join/UbNIjkjp

I'm interested in feedback.

Hi, Thanks for the detailed test case. I can indeed reproduce the issue. I have no idea where it might be coming from, since we're using the Cartopy 0.20.2 release, as is, with no modification. I'm rebuilding with Cartopy 0.20.3 to see if it improves things (realeased on June 29).
