I set the XCode environment variable CFNETWORK_DIAGNOSTICS to 3,according to https://developer.apple.com/documentation/network/debugging_https_problems_with_cfnetwork_diagnostic_loggingand then running the app, I don't see any logs in Xcode debug console.Then, I try to put the codesetenv("CFNETWORK_DIAGNOSTICS", "3", 1);at the start of my main function, and then running the app, I still don't see any logs in Xcode debug console.When I switch the simulator to iOS 12, Xcode debug console output many logs likes: "CFNetwork Diagnostics ....".My Xcode version is Version 11.3.1 (11C504).Is it CFNetwork Diagnostic still available in iOS13?
