How do I get the Mac OS X Firewall to permanently allow my iOS app?

Question

So we want to suppress the following dialog

Do you want the application “NNN.app” to accept incoming network
connections?

which appear on every activation of the Xcode iOS simulator.
I believe there is now a solution for that. Basing my answer on this blog.

Simply run the following commands in a Terminal window:

#temporarily shut firewall off:
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate off

#put Xcode as an exception:
/usr/libexec/ApplicationFirewall/socketfilterfw --add /Applications/Xcode.app/Contents/MacOS/Xcode

#put iOS Simulator as an exception:
/usr/libexec/ApplicationFirewall/socketfilterfw --add /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/MacOS/Simulator

#re-enable firewall:
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --setglobalstate on

For me it worked. Please note simulator address is according to Xcode 8.
