Viewing web Request Details

There is an excellent tool that allows us to view the raw network traffic from the iOS Simulator, Proxyman.

Once downloaded, and installed, you should add Proxyman's root SSL certificate to your MacOS Trust Chain, so that it can decrypt HTTP traffic.

Make a web request with your iOS simulator. Then, Proxyman will detect this request, open the Apps window on the left to view this. From here, click your app. After this, click the request that Proxyman detected. You may have to run this request again for it to work. Then, click the install SSL Certificate button for the app. This certificate will last the duration of this particular iOS Simulator. So once you destory this Simulator, you may need to repeat these steps:

After installing the certificate, restart your app, then make the request a final time. Click the latest request in Proxyman, it will show you the raw headers used for your Simulator, the response returned from the API, the rate limit from the API (5000 daily requests for Yelp) and the time it took to grab the response along with much more data.
