Simulator doesn't try to exactly simulate the GPU from the iOS or tvOS device you are simulating. For example, if you are simulating the iPhone XS, Simulator does not try to emulate the capabilities of an A12 GPU. Instead, Simulator translates any calls you make and directs them to the selected GPU on the host Mac.
In the iOS Simulator, press iOS Simulator in the menu at the top of the screen, and press 'Reset Content and Settings...'. This will clear the entire simulator.
Turning off the Mac network will also help to turn off the iOS Simulator network. You can turn off you Mac Internet connection from System Preferences... → Network and turn off the desired network source. Save this answer.
type: ~/Library/Application Support/iPhone Simulator. The Directories are the iOS version of the different Simulators. The Sub Directories are the Apps install on the simulator.
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
