At least some seems to be build problem.

Do you know what OS iOS claims to be @mdh1418 ? We should perhaps update the OS detection helpers.

This suggest that either we did not copy the supporting file to the device or GetTestFilePath() from TestUtilities returns wrong location. I don't know if there is some good way to triage it @mandel-macaque but that does not look like networking issue.

All the failing mail tests are unicode. Most likely related to #33654 and #33652.

The header file netinet/ip_var.h is missing in iOS SDK. This in turn causes HAVE_NETINET_IP_VAR_H not to be defined and the SystemNative_GetIPv4GlobalStatistics method becomes no-op. I believe the functionality exists on iOS and that someone already filed a bug report about the missing header files.

Similarly, netinet/udp_var.h is missing. Curiously netinet/tcp_var.h exists.
