Temporary solution based on this thread:
rename the file com.apple.nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/UserEventPlugins/com.apple.nsurlsessiond.plugin/
to something -com.apple.nsurlsessiond
and also the file nsurlsessiond(Dont delete) in
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/
to something -nsurlsessiond
