No connection with simulator and localhost #20

I tried to run the sample using simulator and localhost server but app unable to connect, see the screenshot below:

I am not sure is it a problem of iOS simulator restrictions or maybe Info.plist can be tweaked somehow to allow connections to localhost (something with ATS - apple transport security)?

I wanted to check that your sample works OK and then start modifying it as a base template to my needs but I can't pass the first milestone and verify that socket.io works with iOS. I am pretty sure it does but I couldn't verify it for myself with your sample.

What I tried so far:

  1. I tried to follow this answer for react native app connection issue with socket.io but with no luck I then receive another type of error mentioned here
  2. I tried with real device in combination with (1) but still same issue
  3. I tried to set forced update as here proposed in READ.me pod 'Socket.IO-Client-Swift', '~> 15.2.0'

P.S. I want to assure you that I followed your FAQ and didn't modify code of your sample (only for trying (1) and changing server address), so manager instance is global

I finally make it work by deploying your sample server on EC2 aws instance
