How to correctly setup Charles Proxy for the iOS Simulator

From what I can tell most guides online (and even on the Charles website!) are out of date for iOS 17 / Charles Proxy v4.6.6. I’m half making this post just so I can refer to it next time I have a new emulator I need to setup 🤣

Step 1: Install the Root Certificate in iOS Simulators

Help > SSL Proxing > Install Charles Root Certificate

Step 2: Follow the video / steps below

1. Start Charles Proxy
2. Open Safari on your Simulator and visit https://chls.pro/ssl
3. Click Allow on the modal
4. In your simulator Settings > General > VPN & Device Management press the downloaded Charles profile and press Install a few times through the warnings (which are good to note, installing a root certificate for a MITM Proxy is scary business!)
5. Go to Settings > General > About > Certificate Trust Settings
6. Press the Toggle for the Root Certificate you just installed in the ENABLE FULL TRUST FOR ROOT CERTIFICATES section
7. Click Continue on the warning.
8. Thats it!

Step 3: Enable SSL Proxying for some domains

Make sure you setup SSL Proxying for some domains in Proxy > SSL Proxying Settings

You can enable for *:* like you see below if you want proxying for EVERYTHING but I personally don’t like Charles proxying all my requests on my machine out of security concerns

Step 4: Reboot some stuff

Make sure to reboot Charles and your Simulator before trying to attempting to use the proxy!

Thats it! Hope this was helpful (or helpful for future me)
