It seems that the directory for the iOS Simulator has changed. It used to be in ~/Library/Application\\ Support/iPhone\\ Simulator/ and now it\'s in ~/Lib
~/Library/Application\\ Support/iPhone\\ Simulator/
~/Lib
It works for me after go to safari (simulator) and visit the URL:
chls.pro/ssl
Before I had to Install charles root certificate in iOS simulators (Charles: help/SSLproxying)
