Debugging network requests with iOS Simulator, network request data is not showing

I'm not quite sure if it's even possible to do that via web inspector or not but put option 1 just in case. I highly recommend you to go with Option 2 tho.

Option 1

First make sure you don't have anything filtered, then make sure recording is on as shown in picture.

Option 2. RECOMMNDED

Use an http monitoring tool. They are design to do that specific task plus you get many more options such as breakpoints, etc.

• Charles Proxy. (MAC) The best IMHO. You can set breakpoints and alter request/response if needed. And many other features.
• HttpScoop (MAC) Easier to use, but less functionality.
• fiddler (WINDOWS) Just in case.

PS. Some one might say Wireshark, I know but it's too complicated for such work.

[UPDATE 1] To make it clear you don't need to set any proxy on iOS simulator to get these tools working. In case of SSL connections you want to use charles and follow their SSL guideline.
