After successfully installing a cert on iPhone simulator, I still get an SSL error when hitting my web service

Question

I am developing a web service and iOS app that hits the web service on my local machine. At first, I disabled the cleartext errors for interacting with the service, but now I would like to use https so that my development, test, and prod environments are as similar as possible.

I installed my self-signed cert locally, so going to the site directly is using https just fine:

I have followed the instructions to install a cert in the iPhone simulator:

However, when I hit the web service on my local machine that uses this cert, I still get these error in the console:

I have tried restarting the simulator after installing the cert, same result. What am I doing wrong?

It looks like I may not be trusting the cert even after installing it, but I can't find a way to trust it.

Answer 1

The problem is that I had the website cert installed, but not the CA cert generated for my local web server installed. That was as easy as dragging the CA root cert into Safari on the simulator.
