Sorry to revive such an ancient thread, but I just encountered the same thing in macOS. Presumably its the same as on iOS...If you get errors like this in your log, but everything else seems to work OK: (CFNetwork)[318] <Error>: Received XPC error Connection invalid for message type 3 kCFNetworkAgentXPCMessageTypePACQueryIts failing because its trying to download the PAC file for proxy autodiscovery - possibly because your network doesn't support that. So turn off 'Automatic Proxy Discovery'.On MacOS: System Preferences//Network/Wi-Fi/Advanced/Proxies. Uncheck the 'Auto Proxy Discovery' checkbox thereOn iOS: Settings/Wi-Fi/; select the 'i' by the network you use; 'HTTP Proxy/Configure Proxy'. Set it to 'Off'Once I'd done that (on my Mac) these irritating log messages stopped 🙂

"Right. Now that Swift’s runtime is included in the OS, a fix for this will most likely ship as part of an OS update rather than part of Xcode release."Not fixed in macOS 10.14.5 😟

I had the same thing today. Suddenly, randomly, after working for years, I got asked for my github password when trying to 'Push' to the github remote - even though I use SSH rather than passwords.And when I went to preferences/accounts, my github one was grayed out, and gave the same 'Account Unavailable message as you received.I fixed it by completely reinstalling XCode - following these steps I found on the Internet:Delete /Applications/XcodeDelete all files containing com.apple.dt in ~/Library/CachesDelete all files containing com.apple.dt in ~/Library/PreferencesOpen App Store.app, download and re-install Xcode.Create the Apple ID developer accountThat worked fine for me - though other people have reported varying results.I did try just deleing the caches and preferences first, before uninstalling/reinstalling XCode - but that didn't do the trick. I had to do the full re-install thing before it would work.
